Google LLC et al. v. ART Research and Technology LLC

Petitioners Google LLC and YouTube, LLC, both major operating companies providing extensive internet services and online video platforms, initiated an inter partes review (IPR) against ART Research and Technology LLC. Google LLC, a subsidiary of Alphabet Inc., is a multinational technology corporation specializing in search engines, online advertising, cloud computing, and hardware. YouTube, LLC, also a wholly owned subsidiary of Google, is the dominant global video-sharing platform. ART Research and Technology LLC, the patent owner, appears to be a non-practicing entity (NPE) or patent assertion entity (PAE), as it holds the patent at issue and has initiated litigation against Google, but publicly available information does not indicate an operating business directly related to the patent's technology. The IPR was filed in response to a patent infringement lawsuit, ART Research and Technology LLC v. Google, LLC, filed in the Northern District of California (NDCA-3-24-cv-04898).

The IPR challenged claims 1-21 of U.S. Patent No. 9,451,001, titled "Method to Annotate Playable Media Files in a Social Network." This patent broadly describes methods and systems for creating, storing, and displaying annotations within playable media files, such as videos, in a social network environment, including the generation of a table of contents for these annotations. The underlying technology allegedly infringed by Google and YouTube would presumably relate to features on their platforms that allow users to add or interact with annotations on videos, a common functionality within their services. The case was before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO), an administrative tribunal known for providing a faster and often less expensive alternative to district court litigation for challenging patent validity. The PTAB applies a "preponderance of the evidence" standard for unpatentability, which is generally more favorable to challengers compared to the "clear and convincing evidence" standard in federal courts.

The procedural posture of IPR2025-01404 was "Pre-DI Dismissal (Procedural Termination)." This indicates that the petition for inter partes review was withdrawn by Google and YouTube before the PTAB made a decision on whether to institute a trial. This procedural termination is notable, as it occurred after the related district court litigation (NDCA-3-24-cv-04898) was dismissed by stipulated judgment, suggesting a settlement or resolution between the parties led to the IPR's withdrawal. Such linkage between co-pending district court litigation and IPR proceedings is a common strategic element in patent disputes, where the IPR serves as a leverage or defense mechanism against infringement allegations. The involvement of Google and YouTube highlights the ongoing scrutiny of software and internet-related patents asserted against major technology companies.

Legal Developments and Outcome in Google LLC et al. v. ART Research and Technology LLC

The legal proceedings involving Google LLC and YouTube, LLC against ART Research and Technology LLC primarily revolved around a patent infringement lawsuit in district court and a parallel inter partes review (IPR) at the Patent Trial and Appeal Board (PTAB). The IPR, IPR2025-01404, challenging U.S. Patent No. 9,451,001, was ultimately terminated procedurally due to the resolution of the underlying district court litigation.

Key Legal Developments:

District Court Litigation:

• Filing & Initial Pleadings (August 8, 2024): ART Research and Technology LLC initiated a patent infringement lawsuit against Google LLC and YouTube, LLC in the U.S. District Court for the Northern District of California, case number 3:24-cv-04898. The complaint alleged infringement of several patents, including U.S. Patent No. 9,451,001.
• Dismissal (September 29, 2025): The District Court granted Google's motion to dismiss the litigation.
• Final Disposition (November 26, 2025): The district court litigation was terminated pursuant to a stipulated judgment between the parties.

Parallel PTAB IPR Proceedings:

• IPR Filing (August 12, 2025): Google LLC and YouTube, LLC filed a petition for inter partes review, IPR2025-01404, seeking to cancel claims 1-21 of U.S. Patent No. 9,451,001 as unpatentable. The petition argued for obviousness based on several prior art references, including Datar, Zhou, Smith, Gupta, Friedlander, and Mouilleseaux. This IPR was filed shortly after the district court litigation commenced.
• Procedural Termination (December 22, 2025): IPR2025-01404 was marked for "Procedural Termination" by the PTAB. This termination followed Google's unopposed motion to withdraw its petition for IPR.
• Effect of District Court Outcome on IPR: The withdrawal of the IPR petition by Google was a direct consequence of the district court litigation being dismissed via a stipulated judgment. Google simultaneously filed motions to withdraw petitions in other related IPRs challenging patents owned by ART Research and Technology LLC, indicating a broader settlement or resolution between the parties. The Board granted the motion to withdraw, preserving the Board's and the parties' resources since the underlying infringement litigation had been resolved.

Outcome:

The patent infringement litigation between ART Research and Technology LLC and Google LLC, along with its related IPRs, concluded with a stipulated judgment in the district court on November 26, 2025, leading to the procedural termination of IPR2025-01404 on December 22, 2025. The IPR did not reach a decision on institution due to Google's withdrawal of the petition. This suggests an out-of-court settlement or agreement between the parties that resolved all ongoing disputes, including the patent infringement claims and the challenges to the patent's validity at the PTAB.

thought
The user is asking for the counsel of record representing the defendant(s) in the patent infringement case ART Research and Technology LLC v. Google LLC et al., case number 3:24-cv-04898.
The previous sections mention that ART Research and Technology LLC initiated the patent infringement lawsuit, meaning ART Research and Technology LLC is the plaintiff in the district court case. The current task asks for counsel representing the defendant(s) in this patent infringement case, which would be Google LLC and YouTube, LLC.

However, the case context provided at the very beginning of the prompt (the "Case" section) states:
"Caption: Google LLC et al. v. ART Research and Technology LLC
Case number: IPR2025-01404
Court: Patent Trial and Appeal Board (PTAB)
Plaintiff(s): Google LLC; YouTube, LLC
Defendant(s): ART Research and Technology LLC"

This initial "Case" section refers to the IPR case IPR2025-01404, where Google LLC and YouTube, LLC are the Petitioners (often referred to as plaintiffs in an IPR context, challenging the patent) and ART Research and Technology LLC is the Patent Owner (often referred to as defendant in an IPR context, defending the patent).

The "Key legal developments & outcome" section, however, refers to the district court case 3:24-cv-04898, where ART Research and Technology LLC is the plaintiff and Google LLC and YouTube, LLC are the defendants.

The user's current request states: "Identify the counsel of record representing the defendant(s) in this patent infringement case." Given the initial "Case" section refers to the IPR, and in an IPR, ART Research and Technology LLC is listed as the "Defendant(s)", I should interpret "this patent infringement case" as referring to the IPR, and therefore identify counsel for ART Research and Technology LLC.

However, the Key Legal Developments section explicitly discusses a "patent infringement lawsuit in district court" where ART Research and Technology LLC was the plaintiff. The request specifically asks for counsel in "this patent infringement case," which typically refers to the district court litigation. If it refers to the IPR, it would usually be called a "patent validity challenge" or "IPR proceeding."

Let's re-read the request carefully: "Identify the counsel of record representing the defendant(s) in this patent infringement case."
The initial "Case" section provides metadata for IPR2025-01404, where ART Research and Technology LLC is listed as the defendant. In an IPR, the patent owner (ART Research and Technology LLC) is defending its patent, so they are effectively the "defendant" against the petitioner's challenge.

The previous "Legal Developments and Outcome" section clearly distinguishes between the "District Court Litigation" (where ART Research and Technology LLC was the plaintiff) and the "Parallel PTAB IPR Proceedings" (where Google was the petitioner and ART Research and Technology LLC was the patent owner).

If "this patent infringement case" refers to the district court case (3:24-cv-04898), then Google and YouTube are the defendants.
If "this patent infringement case" refers to the IPR case (IPR2025-01404), and "defendant(s)" refers to the party defending the patent, then ART Research and Technology LLC is the defendant.

Given the phrasing "defendant(s)" in the context of "patent infringement case," it's more common to refer to the party accused of infringement in district court as the defendant. In an IPR, the party whose patent is being challenged is the "patent owner." However, the initial "Case" metadata explicitly labels ART Research and Technology LLC as "Defendant(s)" for IPR2025-01404. This is a crucial instruction: "Treat the case metadata in this prompt as authoritative."

Therefore, I will identify counsel for ART Research and Technology LLC in the IPR2025-01404 based on the metadata stating ART Research and Technology LLC is the "Defendant(s)" in this IPR case.

I need to find counsel for ART Research and Technology LLC in IPR2025-01404.
I will use web search to find the counsel for ART Research and Technology LLC in IPR2025-01404.Despite aggressive web searches across various legal databases and public records, the counsel of record representing ART Research and Technology LLC in IPR2025-01404 could not be definitively identified. While ART Research and Technology LLC was the Patent Owner in IPR2025-01404 and the plaintiff in the related district court case 3:24-cv-04898, specific attorneys or law firms representing them in the IPR proceedings are not explicitly named in the available search results.

It is noted that an "Eric Hull" is recorded as having filed a complaint for ART Research and Technology LLC in a different, but related, patent infringement case (3:2023cv02562 against Meta Platforms Inc.). However, this does not directly confirm his or his firm's representation of ART Research and Technology LLC in IPR2025-01404. Given the IPR's procedural termination prior to institution, comprehensive details regarding the patent owner's legal representation may not be readily available in publicly indexed PTAB documents.
