This 27-page specialized invalidity search dossier provides patent defense litigators, PTAB practitioners, and mobile software counsel with a dual-lever tactical advantage. Prepared for high-stakes litigation involving location-based service (LBS) tracking, geo-fencing update protocols, and mobile battery optimization, this report delivers both an unassailable prior art combination under 35 U.S.C. § 103 and a critical priority break argument under 35 U.S.C. § 120 that defeats the patentee’s claimed 2007 filing date. Priority Vulnerability & Invalidity Strategy The subject patent purports to cover an energy-efficient location reporting mechanism where a mobile client reduces network traffic and conserves battery by calculating distance deltas against a minimum threshold, suppressing server updates when stationary, and triggering a low-power sleep mode in the positioning hardware between fixes. Our analysis uncovers a major structural vulnerability in the patent family: the key point of novelty—placing the positioning sensor into a low-power sleep mode when not at a distinct new location—was introduced only in a later CIP filing and provisional application (March 21, 2009) and is entirely absent from the 2007 parent specification. Capitalizing on this critical date shift to March 21, 2009, our global search across patent databases (US, EP, JP, KR, CN, PCT) and academic research (IEEE proceedings and mobile computing literature) establishes a rock-solid multi-reference obviousness strategy under 35 U.S.C. § 103: • Primary Mobile Client Distance-Based Reporting Architecture: A landmark non-patent academic conference publication (published on IEEE Xplore in February 2008, well prior to the March 2009 threshold). This reference discloses a mobile client executing distance-based update (DBU) algorithms, calculating Euclidean distance to the last updated position, suppressing server updates when stationary, and placing the positioning sensor into a low-power sleep mode between fixes. • Primary Subscriber Unit Geo-Fencing & Coordinate Delta Controls: A foundational prior art patent reference detailing a subscriber unit client application that calculates coordinate distances (latitude/longitude) against a configurable Location Delta Threshold (LDT) to control location server updates across various geo-fence boundary geometries. • Primary Embedded Sensor Standby & Power Management: A secondary prior art patent reference teaching dynamic power-saving controls that automatically switch an embedded GPS receiver to standby whenever motion sensors indicate the device is stationary. Exclusive Highlights & Key Strengths of This Report 1. Strategic Priority Break (35 U.S.C. § 120): Includes an explicit legal breakdown demonstrating why the target claims fail the written description requirement for the 2007 parent date, opening the door to statutory bar prior art under pre-AIA § 102(b). 2.

Invalidity Search on US 12,530,925 B2
This report covers all 30 claims of US 12,530,925 B2, which is asserted in trinamiX GmbH v. Apple Inc.. The Claims of Interest are independent claims 1, 17 and 29. The Critical Date is February 18, 2021, the EP priority date. The claims recite a face authentication system with the following elements: a NIR camera with a CMOS sensor; an illumination unit that projects a NIR light pattern through an optical element; a first image used for face detection and a second image of the reflected pattern; a depth check for consistency with a three-dimensional object; a material classification based on comparing light intensity distributions in the pattern image and in a reference image; authentication based on both the depth information and the material classification. The patentee is likely to argue that the novelty lies in the material classification element. This report addresses that element directly. What the report delivers Every claim is charted. All 30 claims, independent and dependent, are rated Category Y. No claim is left as Category A. The three adopted references were all published before the Critical Date. None appears anywhere in the record of the subject patent or its two parent patents, including face citations, IDS and file-wrapper references. The adopted references span three jurisdictions and three distinct technical sources: a European application from a mobile handset manufacturer; a U.S. publication on optical discrimination of living tissue from counterfeit objects; a U.S. publication on facial spoof detection by comparison with stored reference image data. Quotations are verbatim with exact paragraph citations. There is no paraphrase, and each passage is mapped element by element to the claim language. The primary reference is close to the claimed architecture. It describes a smartphone that captures a flood-illuminated infrared image for face detection and a projected-pattern image for depth. It compares the pattern image with a stored reference image, rejects faces that are not three-dimensional, and evaluates skin-related features before authentication succeeds. The report sets out an obviousness rationale for each claim group, including the dependent limitations: the wavelength range, pattern types, remote or local storage of the reference image, a machine-learning model trained to distinguish skin from non-biological materials, failure of authentication on non-biological material, and the optical element configurations. The appendix covers the full search history. It includes CPC classes, keyword blocks in English, Korean, Japanese and Chinese, and the search queries.

Designed for litigation defense counsel and PTAB practitioners, the report evaluates the patentability and obviousness of dual-mode cooling architectures, tiltrotor/fixed-propulsor combinations, and specialized housing ducting configurations under 35 U.S.C. § 103. Search Methodology & Reference Architecture The investigation was conducted across global patent databases (US, EP, JP, KR, CN, PCT) and specialized aerospace literature (AIAA, NASA NTRS) utilizing targeted CPC classifications (including aircraft thermal management, tiltrotor layouts, and electric propulsion cooling). To maximize legal utility, the search strictly excluded every reference cited on the face of the subject patent during prosecution. The report builds a prior art defense framework combining: • Primary tiltrotor nacelle disclosures where heat exchangers are fed by rotor slipstream in hover and airspeed-driven airflow during forward flight. • European aerospace disclosures integrating heat exchangers directly downstream of propulsor fans for electric motor thermal regulation. • Rotorcraft cooling disclosures utilizing rotor-induced low-pressure zones in hover and ram air in forward flight, with perpendicular exhaust geometry. • Prior art distributed propulsion configurations combining forward tiltable rotors with fixed aft rotors or fuselage-embedded lift fans. Key Report Features 1. Exhaustive 1:1 Claim Mapping: Complete claim charts covering all 19 asserted claims, mapping each limitation (such as perpendicular discharge ports, two-stage fluid chambers, and wing-relative propulsor placements) to exact paragraph numbers and figure callouts. 2. Global Multilingual Discovery: Incorporates relevant European, Chinese, and Japanese patent disclosures regarding ducted lift fans and rotor-wash cooling that conventional English-only queries miss. 3. Prosecution History Integrity: Verified to ensure zero overlap with examiner references of record, establishing completely unconsidered obviousness combinations. 4. Structured Legal Rationale: Formulates objective technical motivations to combine based on standard aerospace engineering imperatives to eliminate cooling penalties across both static hover and high-speed forward flight regimes.

This 38-page invalidity search report delivers an objective, highly structured prior art framework designed specifically for patent litigators, PTAB practitioners, and in-house IP counsel defending against digital identity verification and carrier-based authentication claims. Focusing on complex identity graphs where persistent consumer identifiers are linked to multi-aspect digital touchpoints, this dossier provides the evidentiary foundation needed to draft high-probability Inter Partes Review (IPR) petitions or litigation invalidity contentions. Core Technical Architecture & Invalidity Strategy The subject patent claims an identity verifier computing system that receives co-location verification signals from a user device, establishes an identity network anchored by a persistent subscriber identifier, assigns dynamic trustworthiness parameters to interconnecting links, updates those parameters based on user aspect interactions, and returns a location/possession confirmation based on link integrity. Our multi-jurisdictional prior art investigation across US, EP, JP, KR, CN, PCT databases, and specialized NPL archives establishes a clear path to invalidating the claimed identity graph framework under 35 U.S.C. § 103: Primary Mobile Possession & Event Tracking Art: Early disclosures of carrier-based network ID verification utilizing live SIM swap tracking, hardware identifier history (IMEI/IMSI mapping), carrier porting status indicators, and automated risk scoring. Primary Identity Graph & Entity Resolution Art: Prior disclosures establishing persistent consumer link structures across disparate touchpoints (email, IP address, wireline numbers, advertising IDs) with confidence scoring updated through access counts and independent data provider verification. Primary Graph Trust Coefficient Art: Prior social graph frameworks where edge weights and user characteristic scores (trustworthiness/affinity) are dynamically calculated and recalculated based on historical user interactions and neighboring node behavior. Primary Co-Location Verification Art: Early multi-channel authentication systems comparing real-time IP address geolocation against voice communication device geographic coordinates to issue security access scores. Exclusive Highlights & Key Strengths of This Report Zero Patent Prosecution History Overlap: All primary and secondary references were systematically cross-checked and filtered against the face of the subject patent and its complete official prosecution history, providing 100% unconsidered prior art. Multilingual Foreign Art Integration: Unlocks crucial non-English prior art (including Japanese and Asian carrier authentication and graph-scoring patent disclosures) with certified English translations and native text pinpoints. Multi-Pathway Invalidity Combination Frameworks: Offers alternative 3-reference obviousness combinations (e.g., Co-location Primary + Identity Linkage Secondary + Edge Weighting Secondary; and Network History Primary + Identity Linkage Secondary + Edge Weighting Secondary) to adapt flexibly to varying claim construction positions. Detailed Analysis of Deterministic Events: Provides dedicated claim charts mapping deterministic telecommunication events—such as SIM card removal/replacement, carrier porting, device upgrading, and password resets—against historical carrier norm tracking references. Turnkey Work Product: Written to strict attorney-work-product standards, enabling litigation teams to directly extract mapped citations, translated excerpts, and technical combination rationales into legal briefs.
Prior Art Search on US 10,402,874 B1
This 32-page invalidity search report presents a focused, claim-by-claim analysis of U.S. Patent No. 10,402,874 B1, “Aggregator Application App for a Mobile Electronic Device,” covering all 20 claims, including independent claims 1, 8, and 15. The central finding is particularly significant: all 20 claims are assessed as Category Y. The investigation identifies multiple pre-critical-date disclosures which, when considered in relevant combinations, provide a substantial technical basis for challenging the patent’s inventive step under pre-AIA 35 U.S.C. § 102. No Category X reference was identified; the report therefore focuses on combination-based invalidity arguments rather than asserting that a single reference anticipates the claims. Key Features of This Investigation Complete coverage of all 20 claims: Each claim was reviewed and analyzed, with particular attention to the three independent claims and their corresponding dependent-claim limitations. All claims assessed as Category Y: The analysis identifies combination-based challenges across the entire claim set, rather than relying on a limited number of potentially vulnerable claims. Two alternative combinations for the principal claim groups: The report develops distinct combinations of prior-art teachings to address the principal independent claims and their dependent claims. Detailed claim charts: Individual claim elements are mapped to supporting disclosures, with pinpoint citations and explanations of how the cited teachings relate to the claimed subject matter. Independent-claim analysis: Claims 1, 8, and 15 are examined in their respective device, method, and system contexts, with the technical relationships among the limitations addressed. Pre-critical-date verification: The investigation applies the April 9, 2012 critical date and the applicable pre-AIA framework, with publication-date checks for the selected materials. Broader international search coverage: The search considered U.S., European, Japanese, Korean, Chinese, and PCT patent documents, together with relevant non-patent literature. Relevant Chinese- and Japanese-language materials were also reviewed in their original languages. Reference screening: The investigation excluded documents already cited on the face of the subject patent and their family members, focusing the analysis on additional prior-art materials.
Prior Art Search on US 11,391,609 B2
This 46-page invalidity search report provides a detailed, claim-by-claim assessment of U.S. Patent No. 11,391,609 B2, “Flow Meter,” assigned to Sentronics Holdings Limited. The investigation examines all 18 claims, with particular attention to the three independent claims and the technical limitations that distinguish the claimed subject matter from the identified prior art. The report identifies a substantial potential obviousness challenge across the claim set. Sixteen of the 18 claims are assessed as Category Y, based on combinations of multiple prior-art references. The analysis does not rely on a single document disclosing every limitation. Instead, it evaluates how separate technical teachings may be combined to address the claimed measurement method, associated control arrangements, and related apparatus features. The investigation includes: Complete claim coverage: All 18 claims are reviewed, with claim elements and dependency relationships considered in the analysis. Independent-claim analysis: The three independent claims receive focused treatment, including the corresponding method, controller, and flow-meter subject matter. Detailed claim charts: Relevant claim limitations are mapped against the selected references, with pinpoint citations to the supporting passages, claims, and other specific locations. Combination-based obviousness analysis: The report explains the technical basis for combining the selected references and identifies the claim limitations addressed by those combinations. Balanced treatment of limitations: Claims 6 and 7 are separately identified as Category A because the selected references do not expressly disclose their particular additional limitations. Search beyond the patent’s cited references: The investigation considers patent literature across the United States, Europe, Germany, Japan, Korea, China, and PCT publications, together with relevant technical literature. References already of record and their relevant family members were excluded from the adopted-reference analysis. The report applies the April 25, 2016 critical date under the AIA framework and presents the results in a structured format intended to support further patent prosecution, validity, and litigation analysis. For patent attorneys evaluating the strength of the asserted claims, the principal value of this report is its examination of how multiple independent technical disclosures may work together to challenge the scope of 16 claims, while also identifying the limitations that remain less directly addressed. The claim charts and supporting technical reasoning provide a practical starting point for a deeper review of the patent’s potential validity vulnerabilities.
Prior Art Search on US 10,903,734 B1
This 62-page invalidity search report provides a focused, claim-by-claim prior art investigation of U.S. Patent No. 10,903,734 B1, “Delivering Power to Semiconductor Loads,” owned by Vicor Corporation. The investigation addresses 54 asserted claims in connection with USITC Investigation No. 337-TA-1526, involving Vicor Corporation and multiple semiconductor and electronics manufacturers. The report identifies a potentially significant obviousness challenge involving the claimed architecture for delivering power to semiconductor dies through a stacked power-conversion and electrical-interconnection arrangement. Rather than relying on a single general-purpose reference, the investigation develops a multi-reference invalidity theory combining disclosures from different technological approaches. These references collectively address critical aspects of the claimed architecture, including power conversion, electrical interconnection, terminal configuration, multilayer structures, and localized power delivery. Key Findings and Analytical Value 54 asserted claims examined: All asserted claims were decomposed and evaluated, including eight independent claims and their associated dependent claims. 41 claims identified as Category Y: The report identifies substantial potential obviousness challenges based on combinations of independently developed prior-art disclosures. 13 claims identified as Category A: These claims contain limitations for which the selected references provide general background support but do not establish the same level of particular relevance. No Category X reference identified: The investigation does not claim that a single reference independently anticipates the asserted claims. Its principal invalidity position is based on combinations of prior art under the applicable obviousness framework. Four principal prior-art references adopted: The report develops complementary technical teachings into structured combinations addressing the patent's principal claim limitations. What Makes This Report Particularly Valuable The principal value lies in the technical relationship established between the prior-art disclosures and the patent's asserted claim architecture. The analysis examines how previously disclosed semiconductor power-delivery arrangements, conversion circuitry, electrical interface structures, and integrated passive components may be combined to challenge the claimed configuration. Importantly, the report goes beyond identifying potentially relevant publications. It provides claim-element-level comparisons, pinpoint references to the supporting passages, and written explanations of why the identified teachings could be combined by a person having ordinary skill in the art. The independent claims receive particular attention, with separate analyses addressing their respective structural and functional limitations. The dependent claims are also evaluated according to their additional technical features rather than being treated as automatically invalid merely because an independent claim is challenged. Scope and Methodology The investigation covers U.S., European, Japanese, Korean, Chinese, and PCT patent publications using WIPS ON, together with relevant non-patent literature resources. The search incorporates multilingual patent research and classification-based investigation. Publication dates were checked against the applicable bibliographic records, and the subject patent's own family and references already cited on its face were excluded from the adopted prior-art set. The report includes: Subject patent and critical-date analysis. Decomposition of all 54 asserted claims and identification of eight independent claims. Identification of the principal technical limitations and claim relationships. Four adopted prior-art references and additional supporting references. A claim-by-claim relevancy matrix. Detailed claim charts with supporting passages and pinpoint citations. Written obviousness analyses explaining the proposed combinations. A separate assessment of claims for which the selected references do not establish particular relevance. Intended Buyers This report is particularly relevant to patent litigators, PTAB practitioners, in-house patent counsel, and technical experts evaluating potential invalidity positions in semiconductor power-delivery disputes. For counsel assessing the asserted claims, the report provides a structured starting point for investigating multi-reference obviousness theories, identifying vulnerable claim groups, and determining where further technical or legal analysis may be warranted. A substantial claim set, multiple complementary prior-art teachings, and documented claim-level analysis make this report a useful resource for evaluating the strength and potential limitations of the asserted patent claims.
Invalidity Search Report for US11,391,609B2
US11,391,609B2 claims a method, a controller, and a meter for ultrasonic transit-time flow measurement. The independent claims were narrowed during prosecution specifically to get past the prior art — and the patent is now being asserted in U.S. litigation. That narrowing did not save them. This PatKiller invalidity report uncovers earlier disclosures that the examiner never saw: not one of the references relied on was cited in the patent's prosecution history, in any jurisdiction. Mapped element by element against Claims 1, 15 and 16, the art meets every limitation — including the very features the patentee added to secure allowance. WHAT SETS THIS REPORT APART • Two independent anticipation grounds. For every claim of interest, a single earlier reference discloses the complete claimed subject matter, element for element. • Depth behind them. Five additional references, spanning four jurisdictions, are charted in layered obviousness combinations — including a dedicated alternative ground built around the claim feature the patentee will argue matters most. • Litigation-ready claim charts. Every element is tied to verbatim disclosures quoted from the references with pinpoint locations, ready to lift into an IPR petition or a validity brief. • A documented search. Classification and keyword searching across the US, EP, PCT, CN, JP and KR collections, in English, Korean, Japanese and Chinese, with every executed search formula recorded. Every reference predates the patent's earliest priority date of April 25, 2016. If you are defending against this patent, preparing an IPR, or valuing a settlement, this is the art set you need before the other side finds it.

This report presents the results of a worldwide prior art search on the U.S. patent titled “MEMORY PACKAGE HAVING STACKED ARRAY DIES AND REDUCED DRIVER LOAD,” assigned to NETLIST, INC. The patent is asserted against Micron Technology’s HBM3E/HBM4/HBM4E products before the U.S. International Trade Commission (Section 337). The search covered every claim. It included US, EP, CN, JP, KR and PCT patent documents, and IEEE/JEDEC non-patent literature. The independent claims recite a DRAM package in which: stacked DRAM dies are divided into a first and a second plurality, each served by its own command/address and data TSV interconnects; data TSVs of one plurality pass through the dies of the other plurality without connecting to their data ports; a control die couples two conduits to the same data terminal under control logic that responds to C/A signals other than chip select; read-only and write-only unidirectional interconnects link the dies to the control die. The dependent claims add 32/64-bit parallel data, 8- or 16-die stacks, different driver sizes, non-driving states between consecutive read and write operations, timing control against signal collisions, the absence of emulation logic, and group-specific supply voltage interconnects. The critical date is November 3, 2010, the filing date of U.S. Provisional Application No. 61/409,893. Pre-AIA 35 U.S.C. §102 applies, and every adopted reference predates the critical date.
Prior Art Search on US 12,646,537 B1
This analysis examines Claims 1–20 of U.S. Patent No. 12,646,537 B1, “Memory Package Having Stacked Array Dies and Reduced Driver Load,” with a critical date of November 3, 2010, under pre-AIA 35 U.S.C. § 102. The patent is assigned to Netlist, Inc. and concerns a DRAM memory package incorporating stacked memory dies, a control die, and an interface with external terminals. The principal technical feature is the division of stacked DRAM dies into first and second groups, each served by its own command/address (C/A) and data interconnects incorporating through-silicon vias (TSVs). The claimed architecture separates the interconnects serving the two groups and uses signal conduits in a control die positioned between the stacked dies and the package interface to drive corresponding data and C/A signals concurrently. Independent Claim 14 further addresses connecting interconnects from both groups to the same package terminal through separate conduits controlled by logic in the control die. The dependent claims add limitations involving data-terminal width and die count, separate supply-voltage interconnects, unidirectional write and read paths, differing driver strengths, and control of the conduits connected to a shared terminal. The investigation reviewed U.S., European, Japanese, Korean, Chinese, and PCT patent documents, together with relevant IEEE and JEDEC technical literature. The search used classification-based and multilingual keyword strategies, and the candidate references were checked for publication-date eligibility against the November 3, 2010 critical date. References already cited on the subject patent were excluded from the adopted-reference analysis. The report identifies four principal prior-art references and evaluates their relevance to the claimed memory-package architecture. The analysis focuses on whether the combination of independently interconnected DRAM groups, concurrent signal driving, and controlled shared-terminal connections could have been derived from the prior art.

This analysis examines Claims 1–20 of U.S. Patent No. 12,200,816 B2, “Transmitting a Complement of User Parameters to a Communications Device,” with a critical date of January 7, 2021, under AIA 35 U.S.C. § 102. The subject patent concerns a system for verifying possession of a mobile device, generating operation-specific temporary identifiers subject to usage restrictions, and transmitting personally identifiable information (PII) to a communications device for automatic completion of user information fields. The claimed technology combines identity verification, temporary authentication credentials, and automated delivery of user information. The analysis evaluates prior art addressing carrier-assisted identity verification and PII pre-fill, temporary authentication numbers associated with specific verification requests, short-lived single-use authorization codes, and user identification with automatic form completion, including QR-code-initiated workflows. No single reference was identified as disclosing every element of the claimed combination. However, the analysis identifies potential obviousness grounds based on combinations of the cited prior art. The principal issue is whether the combination of operation-specific, use-count-limited identifiers with established identity-verification and PII pre-fill techniques would have been obvious to a person skilled in the art.

This report presents the results of a prior art search and technical invalidity analysis concerning systems and methods for determining and displaying patient-specific coronary blood flow characteristics. The subject patent relates to using patient-specific cardiac image data to create a model of blood flow through a coronary artery and to determine blood flow characteristics, including velocity, pressure, flow rate, or fractional flow reserve (FFR), without invasive pressure measurement. The claims further address an electronic display presenting at least three parallel, coextensive representations of the same artery segment: a blood-flow-characteristic graph plotted along a proximal-to-distal axis, an anatomical image aligned with that axis, and a model of the artery displaying the corresponding value at its location. The investigation reviews all 18 claims, including the independent system, computer-implemented method, and computer-readable-medium claims. The analysis focuses on coronary artery modeling, computational fluid dynamics, CT-based non-invasive FFR estimation, pressure and distance graphs, vessel-image visualization, and the alignment of physiological measurements with anatomical representations. Four principal prior art references were selected for detailed analysis. D1 describes coronary artery lumen imaging, computational flow modeling, pressure-versus-distance graphs, and three-dimensional vessel representations. D2 addresses CT-based simulation of FFR values at multiple coronary artery locations without an invasive pressure wire. D3 describes vessel visualization using color-coded physiological measurements and the coordinated presentation of vessel images, pressure graphs, and three-dimensional models. D4 discloses calculating CT-FFR values at locations along a three-dimensional vessel model and displaying those values in association with the corresponding anatomical locations.

Prior Art Search on US 9,092,075 B2
This report provides a technical assessment of prior art relevant to U.S. Patent No. 9,092,075 B2, entitled “Fingertip Mouse and Base.” The investigation focuses on identifying earlier disclosures that may challenge the inventive contribution of the claimed finger-worn input device. The patented technology concerns a wearable computer input system that tracks finger movement and communicates the resulting information wirelessly to a separate computing device. Its principal claim combines a finger-receiving housing, internal electronic components, wireless communication circuitry, accelerometer-based motion detection, a user-activated selection mechanism, and a display mounted on the housing. The dependent claims extend this configuration to include host-side display control, thumb-operated input, an additional accelerometer for selection, electrical charging through a base, a finger-enclosing housing, supplementary display functions, device-status indications, incoming wireless communications, and scrolling through available functions. The report uses November 5, 2004 as the critical date and applies the pre-AIA statutory framework as identified in the underlying investigation. The search examined patent publications from the United States, Europe, Japan, Korea, China, and the PCT system, alongside screening of relevant non-patent technical literature. Candidate references were also checked against the subject patent's cited documents and related patent family. The analysis concentrates on the combination of features that distinguishes the claimed device: motion sensing within a finger-worn structure, wireless interaction with a host computer, on-device visual output, and user-operated selection functionality.
Prior Art Search Report on US 2023/0378460 A1 — Cathode for Lithium Secondary Battery
US 2023/0378460 A1 (SK On) is a pending application claiming a lithium-secondary-battery cathode built on single-particle lithium metal oxide plus a two-step high-then-low calcination, with a novel FIB-based crystal-size parameter (S/N, 1-3 um) and an XRD peak-intensity ratio. This 21-page prior-art search report was prepared BEFORE registration to secure killer prior art in advance — so the buyer is ready the moment the patent grants. KEY FINDINGS: method claims 10-13 are anticipated (X) — a US university publication discloses the hydroxide-plus-lithium-source, 970C/4h-then-780C/10h process step for step, and a third-party Chinese patent published 12 days before the critical date independently anticipates claims 10-12. Product claims 1-9 fall as obvious (Y) over combinations covering the single-crystal/polycrystalline blend, the identical XRD I(110)/(003) ratio formula, and matching half-cell capacity data. The report is candid about its limits: no reference reports the FIB-based S/N metric; the applicant's own XRD-ratio patent sits inside the US grace period (fully citable in EP opposition); the repeated-calcination claims (14-15) rest on a motivation argument. INCLUDES: verified verbatim citations with exact paragraph locations, per-claim X/Y/A ratings, 12-formula WIPS Global search history (EN/KO/JA/CN), and a full additional-references set. BEST USE: file away now; deploy in EP opposition against EP 4280303 A1 or US post-grant review/IPR the moment the patent issues.

The Critical Date was fixed at October 11, 2006 (U.S. filing date; no earlier priority claimed), and the public-availability/priority date of every candidate was independently verified against first-source records. One highly on-point candidate (a Korean-priority document disclosing use of the word-line read voltage as an initial voltage before program ramp-up) was verified to post-date the Critical Date by one day and was accordingly excluded as ineligible. Four Most Relevant References (D1-D4) and four Additional References were identified. No single reference discloses every element of any independent claim; accordingly, no claim is anticipated (Category X). The invalidity theory is therefore based on obviousness (Category Y), supported by verbatim, precisely-located disclosures mapped element-by-element in the claim charts. Claims that could not be tied to an explicit prior-art disclosure are transparently marked Category A. The report (approx. 17 pages) includes: full subject-patent bibliographic and search-strategy information; a Most Relevant / Additional References table with X/Y/A categorization; a full Claim 1-19 Relevancy Matrix; detailed claim charts for all three independent claims (1, 6, 12) and every dependent claim, each quoting the prior-art text at its exact location (claim number, figure, section/paragraph); and a complete search-history appendix (multilingual keyword sets, Boolean/proximity queries, and databases).

All references of record and all references cited during prosecution of the subject patent were excluded from the search results. Every claim element was mapped to prior art only where the reference expressly discloses that element at an identifiable location, with the matching disclosure quoted verbatim together with its exact source location (figure, section, or passage). No paraphrased or merely suggestive disclosure was treated as anticipatory.
Invalidity Search Report for US9804819B2
This report provides the results of a comprehensive worldwide prior art search relating to the U.S. patent titled "RECEIVING APPARATUS AND CONTROL METHOD," U.S. Patent No. 9,804,819 B2, assigned to SOUNDCLEAR TECHNOLOGIES LLC (original applicant: JVC Kenwood Corporation). The search was conducted to identify prior art references relevant to all claims of the subject patent, including patent documents and publicly available technical disclosures worldwide. The subject patent is directed to a volume-lock control for a receiving apparatus in which, from the locked state, turning on a predetermined operating part switches to the non-locked state only when the operating value comes within a predetermined range based on the stored lock value (soft-takeover / pickup), and turning the operating part off updates the lock value and returns the apparatus to the locked state — thereby preventing a sudden volume jump upon re-adjustment. The Critical Date was fixed at December 7, 2015 (earliest effective filing date = Japanese priority date, JP 2015-238210). Only references publicly available before this date were treated as eligible prior art, and every reference cited on the face of the subject patent was excluded. The purpose of this search is to locate potentially relevant prior art that may impact the novelty and/or inventive step of the claimed invention.
Invalidity Search Report for US9123034B2
This report provides the results of a comprehensive worldwide prior art search relating to the U.S. patent titled "METHODS AND SYSTEMS FOR ELECTRONIC PAYMENT FOR PARKING USING AUTONOMOUS POSITION SENSING," assigned to Transparent Wireless Systems, LLC. The search was conducted to identify prior art references relevant to all claims of the subject patent, including patent documents and publicly available technical disclosures worldwide. The purpose of this search is to locate potentially relevant prior art that may impact the novelty and/or inventive step of the claimed invention. The subject patent is directed to a mobile parking-payment system in which a handset or in-vehicle platform determines the parking location by satellite positioning, automatically senses the vehicle's identity from a distinct in-vehicle device over near-field/short-range wireless, allows the user to override the sensed position by designating an alternative location on-screen (which is set as the parking spot and initiates the session), and supports handheld enforcement and automatic session termination. The critical date is April 23, 2012 (earliest effective filing date; pre-AIA). All adopted references were published before the critical date and, per §325(d) risk-mitigation policy, none was cited or considered during prosecution of the subject patent. Every adopted reference and every quoted disclosure was verified against the primary document. Four killer references were identified: US Reference (D1), US Reference (D2), US Reference (D3), and US Reference (D4). Specific reference identities are disclosed to the buyer upon purchase.
Invalidity Search Report for US10783506B2
This report provides the results of a comprehensive worldwide prior art search relating to the U.S. patent titled "Methods and Systems for Access Control to Secure Facilities" (US 10,783,506 B2), assigned to Transparent Wireless Systems, LLC. The search was conducted to identify prior art references relevant to all claims (1–32) of the subject patent, including patent documents and publicly available technical disclosures worldwide (US/EP/CN/JP/KR/PCT and non-patent literature). The subject patent is directed to controlling access at a gated facility using a plurality of Bluetooth Low Energy (BLE) beacon modules that receive advertisement packets carrying a handset/user identifier, time-average the per-beacon received signal strength indication (RSSI), report the identifier and RSSI to a server, and have the server select — among several handsets queued at different distances — the one most likely to occupy the expected location at the gate, authenticate only that handset, and open the gate. The purpose of this search is to locate potentially relevant prior art that may impact the novelty and/or inventive step of the claimed invention, with particular attention to references not considered during prosecution. All references adopted below are non-examiner-cited and fall outside the subject patent's file history.
Invalidity Search Report for US8423235B2
This report provides the results of a comprehensive worldwide prior art search relating to the U.S. patent titled "VIDEO RECORDING DEVICE FOR VEHICLE AND DRIVING INFORMATION PROVIDING METHOD THEREOF" (US 8,423,235 B2), assigned to Mtekvision Co., Ltd. The search was conducted to identify prior art references relevant to all claims of the subject patent (claims 1–17), including patent documents and publicly available technical disclosures worldwide. The critical date for this analysis is September 14, 2009 (the Korean priority date), and only references publicly available before that date were adopted. To preserve the report's value for an inter partes review petition, every reference appearing on the face of the subject patent and its background — as well as the examiner-cited Rayner family — was deliberately excluded, so that all adopted art is non-redundant under 35 U.S.C. § 325(d). The subject patent's alleged point of novelty is a camera-equipped vehicle recorder that generates two different sets of driving information depending on whether the vehicle is in use or in nonuse, the minimal nonuse set being produced by periodically waking the device on an auxiliary power supply and used to verify that the recorder has not been disabled. The report adopts five verified killer references (D1–D5) and four corroborating additional references, with full element-by-element claim charts and a claims-by-references relevancy matrix. No single reference anticipates the independent claims, so the grounds are presented as obviousness grounds under § 103.
