Google LLC v. Accusearch Technologies LLC

Google LLC, a global technology conglomerate, is the petitioner in this Inter Partes Review (IPR). The company is widely known for its extensive range of internet-related services and products, including its dominant search engine, online advertising technologies, cloud computing, software, and hardware. The respondent, Accusearch Technologies LLC, operates as a public records research and private investigation agency, specializing in Arizona and Nevada. However, in the context of patent litigation, Accusearch Technologies LLC appears to function as an Intellectual Property assertion entity (also known as a Patent Assertion Entity or Non-Practicing Entity), having filed its first litigation against Google concerning "Google Search Engine Products and Services" in the District of Delaware.

This IPR, IPR2026-00286, was filed on March 6, 2026, at the Patent Trial and Appeal Board (PTAB) and is currently pending. It concerns US Patent 10585999, which falls under Technology Center 2100, generally encompassing Computer Architecture, Software, and Information Security. While the specific Google product, service, or technology accused of infringement in the underlying district court litigation that prompted this IPR is not explicitly detailed in the immediately available IPR records, AccuSearch Technologies LLC's prior litigation against Google accused "Google Search Engine Products and Services" such as the Google website, Chrome browser, and related legacy products for allegedly providing annotated Internet search results suitable for display on computing devices. This suggests the challenged patent likely pertains to aspects of Google's search and display functionalities. A one-line technical sketch of US Patent 10585959, based on its classification within Computer Architecture, Software, and Information Security, would generally relate to methods or systems for processing and presenting information, potentially in a search-related context. (A more specific technical sketch would require direct access to the patent's claims and specification, which are not provided in the search results).

The procedural posture of this case is an Inter Partes Review before the PTAB, a specialized tribunal within the United States Patent and Trademark Office (USPTO) that reviews the patentability of issued patent claims. The IPR was filed by Google, often a petitioner in such proceedings to challenge the validity of patents asserted against it in parallel district court litigations. The PTAB serves as a critical venue for challenging patent validity based on prior art, and its decisions can significantly impact the trajectory of related infringement lawsuits. The case is notable due to Accusearch Technologies LLC's apparent role as a Patent Assertion Entity, initiating litigation against a major technology company like Google, and Google's common strategy of employing IPRs to challenge asserted patents, aiming to invalidate them and thus mitigate infringement liability.The case, Google LLC v. Accusearch Technologies LLC, IPR2026-00286, is an Inter Partes Review (IPR) filed at the Patent Trial and Appeal Board (PTAB). Google LLC, the petitioner, is a multinational technology corporation renowned for its extensive internet-related services and products, including its search engine, online advertising, cloud computing, and various software and hardware offerings. Accusearch Technologies LLC, the patent owner, primarily operates as a public records research and private investigation agency in Arizona and Nevada. However, in the context of patent litigation, Accusearch Technologies LLC has acted as a Patent Assertion Entity (PAE), having previously filed its initial litigation against Google concerning "Google Search Engine Products and Services".

The specific patent at issue in this IPR is US Patent 10585959. While a detailed technical sketch of the patent is not directly available in the search results, its classification within Technology Center 2100 (Computer Architecture, Software, and Information Security) suggests it generally pertains to methods or systems for information processing and presentation. In Accusearch's prior litigation against Google, the accused products and services included "Google Search Engine Products and Services" like the Google website and Chrome browser, specifically targeting features related to "providing annotated Internet search results suitable for display to a user on a computing device". Therefore, the accused technology in this IPR likely relates to Google's search and information display functionalities.

This IPR was filed on March 6, 2026, and is currently pending before the PTAB. The PTAB is an administrative tribunal within the USPTO responsible for reviewing the patentability of issued claims, particularly through trial proceedings like IPRs. The choice of the PTAB as a venue is significant because IPRs provide an efficient mechanism for challenging patent validity based on prior art, often running in parallel with district court infringement actions. This case is notable due to the involvement of Accusearch as a PAE asserting patents against a major operating company like Google, and Google's consistent strategy of utilizing IPRs to challenge the validity of patents that are asserted against its products, aiming to neutralize potential infringement claims.

Parallel IPR Proceeding Filed Against Accusearch Technologies' Patent Amidst Delaware Litigation

Washington, D.C. – May 29, 2026 – Google LLC has initiated an Inter Partes Review (IPR) proceeding, IPR2026-00286, against Accusearch Technologies LLC, challenging the validity of US Patent 10585959. The petition was filed with the Patent Trial and Appeal Board (PTAB) on March 6, 2026, and is currently pending an institution decision. This IPR follows a patent infringement lawsuit filed by Accusearch Technologies LLC against Alphabet (Google) in the District of Delaware on April 29, 2025 (Case No. 1:25-cv-00514).

Key Legal Developments:

District Court Litigation (Accusearch Technologies LLC v. Google LLC, D. Del. 1:25-cv-00514)

• Filing of Complaint (2025-04-29): Accusearch Technologies LLC filed its first patent infringement lawsuit, accusing Alphabet (Google) of infringing four patents related to "annotated Internet search results" through "Google Search Engine Products and Services," including the Google website and Chrome browser. While the specific list of all four asserted patents was not immediately available, it is highly probable that US Patent 10585959, the subject of Google's IPR, is among them.
• Initial Pleadings: Details on Google's answer or any counterclaims in the Delaware district court case are not yet publicly detailed in the available search results.
• Pre-trial Motions: As of May 29, 2026, there are no public records indicating that Google has filed a motion to stay the district court litigation pending the outcome of the IPR.

PTAB Inter Partes Review (Google LLC v. Accusearch Technologies LLC, IPR2026-00286)

• Petition Filing (2026-03-06): Google LLC filed the IPR petition challenging US Patent 10585959.
• Status: Pending Institution Decision: The case is currently in the pre-institution phase. The PTAB typically issues a decision on whether to institute an IPR approximately six months after the petition filing date. Therefore, an institution decision for IPR2026-00286 is not expected until around September 2026.
• Filings: An Exhibit 2012 was filed in the IPR on May 13, 2026.

Outcome:

Both the district court litigation and the parallel IPR proceeding are in their early stages. The district court case is proceeding, and the PTAB has yet to decide whether to institute the IPR. No claim construction, discovery milestones, trial events, or final dispositions have occurred for either case at this time. The ultimate outcome of the IPR, once an institution decision is made and a final written decision is potentially issued, could significantly impact the ongoing district court infringement litigation. Recent changes in PTAB policy, including the USPTO Director's increased involvement in institution decisions and new considerations for discretionary denials related to U.S. manufacturing activity and "settled expectations," may influence the IPR landscape.

I'll research counsel of record for the petitioner (Google LLC) in IPR2026-00286 and the related district court action.

Let me dig into the IPR docket and the district court docket for Google's counsel.

Now let me pin down the IPR petitioner's lead counsel and the district court defense team.

Counsel of Record — Petitioner/Plaintiff Side (Google LLC)

Threshold clarification. The case metadata here designates Google LLC as the plaintiff (petitioner) and AccuSearch Technologies LLC as the defendant (patent owner), and the prior section covered AccuSearch's representatives. Note the role inversion in the parallel district court action: there, AccuSearch is the plaintiff and Google is the defendant (AccuSearch Techs. LLC v. Google LLC, No. 1:25-cv-00514-GBW, D. Del.). I therefore report Google's counsel in both fora, and add the fuller AccuSearch roster as an enrichment to the earlier "Defendant representatives" section.

1. PTAB — IPR2026-00286 (Google as Petitioner)

Supporting pattern evidence for Wolf Greenfield as Google's PTAB counsel of record (analogous, not this case): Google LLC v. EcoFactor, Inc., IPR2023-00356 (Smith Baluch for Google — showing Google bifurcates PTAB counsel by case); Google LLC, IPR2021-00155 (POA naming Elisabeth H. Hunt, Richard F. Giunta, Anant K. Saraswat, Nathan R. Speed, Gregory F. Corbett of Wolf, Greenfield & Sacks, USPTO Customer No. 23628); Google LLC v. Security First Innovations LLC, IPR2024-00215 (Lead Counsel for Google: Elisabeth H. Hunt; Back-up: Gregory S. Nieberg and Nathan R. Speed, Wolf Greenfield).

Parallel IPRs with the same counsel designation: IPR2026-00287 ('001 patent) and IPR2026-00289 ('937 patent) — same parties, both also carrying a Petitioner Notice of Intent to Designate Nathan R. Speed … as Back-up Counsel. The three IPRs map to three of the four patents asserted in Delaware (the '959, '001, and '937 patents).

Caveat: I could not open the PACER/PTAB "PAPER" docket for IPR2026-00286 directly; the counsel identification above rests on docket-aggregator listings (Docket Alarm) and on the petition/POA content available through secondary databases. If a substitute or updated § 42.10(b) power of attorney has been filed, it would supersede the March 6, 2026 paper.

2. District Court — AccuSearch Technologies LLC v. Google LLC (Google's defense team)

Per the CourtListener docket for 1:25-cv-00514 (D. Del., Judge Gregory B. Williams), Google-side counsel appearing includes:

Docket anchors: D.I. 20 (motion to transfer to N.D. Cal.), D.I. 26 (motion to dismiss under Rule 12(b)(6)/§ 101), D.I. 39 (motion for pro hac vice of Emily Hasselberg), and the Aug. 28, 2025 CM/ECF entry adding Porto, Hayward, Schneider, Bayley, and Silbert for Google LLC for electronic noticing. Scheduling order signed Sept. 4, 2025 (Markman Oct. 21, 2026; fact discovery closes Feb. 26, 2027; trial Apr. 17, 2028).

Important limitation: the district-court counsel names above come from docket-text snippets, not from a reviewed attorney appearance/PACER party report. Firm affiliations for the Google-side team are my inference from attorney rosters, not something I confirmed in a source during this research, and are flagged accordingly. No attorney has been fabricated.

3. Enrichment / correction to the prior "Defendant representatives" section

The earlier section listed AccuSearch's counsel but omitted three of the attorney names appearing on the Rule 7.1 disclosure and pro hac vice motion (D.I. 4, 6): the full AccuSearch team is Ronald M. Daignault, Chandran B. Iyer, Oded Burger, Steven J. Reynolds, and Lisa Phillips of Daignault Iyer LLP, 8229 Boone Blvd., Suite 450, Vienna, VA (of counsel; each moving pro hac vice), plus Andrew C. Mayo (#5207) and Brian A. Biggs (#5591) of Ashby & Geddes, 500 Delaware Ave., 8th Floor, Wilmington, DE as Delaware counsel of record. (Snippets also show Iyer's address as cbiyer@daignaultiyer.com, correcting the earlier "not stated" note.) Daignault Iyer is a well-known patent-assertion boutique; Reynolds is former Federal Circuit staff.

Open items requiring PACER/PTAB direct access

1. Lead counsel name for IPR2026-00286 (Paper 1, Power of Attorney, Mar. 6, 2026) — retrieve the paper text to confirm whether Elisabeth H. Hunt or another Wolf Greenfield attorney is lead.
2. Any subsequent § 42.10(b) substitution or pro hac vice motion in IPR2026-00286 (e.g., for a Wolf Greenfield attorney not yet admitted to the PTAB bar).

It's important to note that while these attorneys are listed as counsel in the district court litigation, specific appearances for the IPR (IPR2026-00286) at the PTAB would be recorded on the PTAB's Public Access to Proceedings (PAPE) system docket. As of today's date, the full details of counsel appearing for Accusearch Technologies LLC in the IPR are not readily available in public search results.

Robert Osann Jr., the sole inventor of the patent at issue (US 10585959), previously assigned the patent to Accusearch Technologies LLC. He has extensive experience in IP consulting, including patent searching, application drafting, and expert witness services in patent litigation, where he has acted as an expert witness for patent validity. However, his role in the current IPR is likely as the inventor and potentially an expert, rather than as legal counsel.
