Untitled case

The patent infringement lawsuit, 1:24-cv-00552, was filed by STERLING COMPUTERS Corp. (Plaintiff) against X Corp. (formerly Twitter, Inc.) (Defendant) in the U.S. District Court for the Western District of Texas on May 22, 2024.

STERLING COMPUTERS Corp. is described as a global solutions integrator and value-added reseller (VAR+) of IT equipment, software, and services, primarily serving government, education, and commercial clients, with a focus on cybersecurity and advanced technologies. While primarily an operating company, Sterling Computers has recently engaged in patent litigation, filing suits against major tech companies. X Corp. is a well-known social media company, operating the platform "X" (formerly Twitter).

The asserted patent in this case is U.S. Patent No. 7,716,217, titled "Determining relevance of electronic content". Generally, the patent relates to a system and method for determining a "relevance score" for electronic content sent to a user by monitoring user actions and/or the actions of other users in the system. The accused products are X Corp.'s content recommendation and ranking systems on its social media platform.

The case was initially assigned to Judge Robert Pitman but was subsequently reassigned to District Judge Alan D. Albright for all proceedings on March 27, 2025. The Western District of Texas, particularly the Waco Division under Judge Albright, has been a popular venue for patent plaintiffs due to its streamlined patent litigation rules and Judge Albright's extensive experience and interest in patent cases. This case is notable as part of a pattern of patent assertions by Sterling Computers, which also filed a related suit against Meta Platforms (1:24-cv-00551) over the same patent and a separate case against Microsoft in April 2024 (1:24-cv-00406) involving a different patent. X Corp. has also initiated an inter partes review (IPR2025-00299) of the '217 patent at the Patent Trial and Appeal Board (PTAB), with the institution decision issued on June 10, 2025.

Sterling Computers Corp. (Plaintiff) filed a patent infringement lawsuit against X Corp. (formerly Twitter) (Defendant) in the Western District of Texas, concerning U.S. Patent No. 7,716,217 ("the '217 patent"). The patent generally relates to determining a "relevance score" for electronic content sent to a user.

Here are the key legal developments and outcomes:

There is an active IPR proceeding (IPR2025-00299) challenging the asserted patent (U.S. Patent No. 7,716,217), with a trial having been instituted on June 10, 2025. The impact of the instituted IPR on the district court litigation, such as a potential stay, is not explicitly detailed in the provided search results but is a common development in such scenarios.## Key Legal Developments and Outcome for STERLING COMPUTERS Corp v. X Corp. (1:24-cv-00552)

This patent infringement lawsuit, filed by STERLING COMPUTERS Corp against X Corp. (formerly Twitter) in the Western District of Texas, concerns U.S. Patent No. 7,716,217 ("the '217 patent"), which generally relates to determining a "relevance score" for electronic content sent to a user.

Chronological Developments:

• 2024-05-22: Complaint Filed. Sterling Computers Corporation initiated the lawsuit against X Corp. (f/k/a Twitter, Inc.) in the U.S. District Court for the Western District of Texas, assigned Case No. 1:24-cv-00552. The complaint alleges that X Corp. infringes the '217 patent through its content recommendation and ranking systems. This case is part of a broader patent enforcement effort by Sterling Computers, which also filed a similar suit against Meta Platforms (1:24-cv-00551) on the same day and a prior suit against Microsoft (1:24-cv-00406) in April 2024. The '217 patent was acquired by Sterling Computers in September 2014 from Bluespace Software.

• 2024-12-12: IPR Petition Filed by X Corp. X Corp. filed a Petition for Inter Partes Review (IPR) with the Patent Trial and Appeal Board (PTAB), challenging claims of the '217 patent. This initiated PTAB proceeding IPR2025-00299.

• 2025-03-27: Case Reassigned to Judge Alan D. Albright. The district court case, 1:24-cv-00552, was reassigned to Judge Alan D. Albright for all further proceedings.

• 2025-04-XX: Motion to Stay Pending IPR Filed by X Corp. X Corp. filed a motion to stay the district court proceedings pending the outcome of the IPR challenging the '217 patent.

• 2025-06-10: IPR Trial Instituted (IPR2025-00299). The PTAB instituted an Inter Partes Review (IPR) trial for IPR2025-00299, challenging claims of the '217 patent. The PTAB determined that the IPR would proceed on all asserted claims and all grounds of unpatentability. In the institution decision, the PTAB indicated it would interpret claim terms using the same standard as a civil action under 35 U.S.C. 282(b), giving words their ordinary and customary meaning as understood by a person of ordinary skill in the art. The PTAB also noted the existence of a parallel IPR (IPR2025-00430) filed by Meta Platforms, Inc. challenging the same patent.

• 2025-09-22: Related IPR Trial Instituted (IPR2025-00270). In a related case involving Sterling Computers' '911 patent (asserted against Microsoft), the PTAB also instituted an IPR trial (IPR2025-00270) challenging claims of that patent.

• 2026-04-05: Tentative Trial Date. The district court case (1:24-cv-00552) has a trial tentatively set for April 5, 2027.

Outcome / Present Posture:

The patent infringement litigation (1:24-cv-00552) is currently active in the Western District of Texas before Judge Alan D. Albright. While a motion to stay the district court proceedings pending the outcome of the IPR (IPR2025-00299) was filed by X Corp., the specific outcome of that motion is not detailed in the provided search results. Given that the IPR was instituted on June 10, 2025, and a trial date of April 5, 2027, has been set for the district court case, it is plausible that a stay might have been denied or has specific conditions, or that the court is proceeding with certain pre-trial activities. The PTAB is expected to issue a Final Written Decision for X Corp.'s IPR (IPR2025-00299) around June 2026. The existence of this IPR and its eventual outcome will significantly influence the trajectory of the district court litigation, particularly regarding the validity of the '217 patent. The case has not yet reached claim construction.

I'll research the plaintiff's counsel of record through multiple searches.

Key leads: DiNovo Price LLP (plaintiff's counsel) and local counsel in Waco. Let me dig deeper.

Now let me pull the full docket entries and confirm each attorney's firm and role.

Plaintiff's Counsel of Record — Sterling Computers Corporation v. X Corp., No. 1:24-cv-00552 (W.D. Tex.)

The plaintiff's litigation team is a two-firm combination: DiNovo Price LLP (Austin, TX) as the Texas-based district-court firm, and Padmanabhan & Dawson, PLLC (Minneapolis, MN) as the patent-focused/pro hac vice group that also serves as Patent Owner's counsel in the parallel PTAB proceedings on the '217 patent.

The core docket entries establishing these appearances are the pro hac vice admission motions filed with the complaint on May 22, 2024 (Dkt. 10–12) and the corresponding May 24, 2024 orders granting them (Dkt. 13–16), plus the transcript of the case's in-court hearing, where appearances were stated on the record.

Caveats and gaps (please read before relying on the above)

1. Andrew G. DiNovo — The name partner of DiNovo Price LLP is the firm's founder and a well-known Waco/Austin patent litigator, and industry coverage of this suit states that "DiNovo Price LLP represents Sterling" (Mondaq, July 2024). However, I did not find a docket entry showing him appearing of record in 1:24-cv-00552, and I will not represent him as counsel of record on that basis alone. His name may appear on the complaint signature block or a later notice of appearance not captured in the docket snapshot I retrieved.

2. Docket snapshot is stale. The public Justia docket I could retrieve runs only through July 15, 2024. Additional appearances (or withdrawals) after that date — including any resulting from the March 27, 2025 reassignment to Judge Albright, the stay proceedings, or the IPR coordinating activity — would not appear in that snapshot. Confirm current appearances against PACER before filing or relying on this list.

3. Firm affiliation for Robbennolt and Loftus is unverified. Their pro hac vice motions were filed by the same Texas counsel (Goodpastor) and granted in the same order batch as Padmanabhan and Sankaran, which strongly suggests the same Minneapolis PTAB group, but I have no retrieved source confirming their employer. These are the two names most in need of PACER confirmation.

4. No in-house counsel identified. No appearance by a Sterling Computers in-house attorney (e.g., its general counsel or CFO/secretary-level signatory on corporate filings) was located. Corporate documents show Paige Marks signing the IPR power of attorney for Sterling, but that is a corporate-execution signature, not a litigation appearance.

5. PTAB counsel overlap. In the IPRs on the '217 patent, Sterling is represented by Padmanabhan (lead) and Michelle E. Dawson (backup) of Padmanabhan & Dawson — not by DiNovo Price. If you are tracking the full Sterling legal team across venues, the IPR roster is a separate (though overlapping at Padmanabhan) list.

⚠️ Contradiction to flag against the previously generated "Defendant representatives" section

The earlier section identifies X Corp.'s counsel of record as David McCombs (Haynes and Boone), Quinn Emanuel, and Kirkland & Ellis. The district-court docket for this case does not support that. The X Corp. appearances docketed here are:

• Yar R. Chaikovsky — Notice of Attorney Appearance, Dkt. 20 (July 15, 2024); signed X Corp.'s Answer (Dkt. 23) and Rule 7 Disclosure Statement (Dkt. 24)
• David T. Okano — Notice of Attorney Appearance, Dkt. 21 (July 15, 2024); stated appearance on the record for X Corp.
• Radhesh Devendran — Notice of Attorney Appearance, Dkt. 22 (July 15, 2024)

At the hearing, defense counsel stated: "For defendant, David Okano at White & Case for Defendant X Corp. With me is Ethan Plail and Brady Schoenlein." So the defense side of record appears to be White & Case (Chaikovsky, Okano, Plail, Schoenlein, Devendran), not Haynes and Boone/Quinn Emanuel/Kirkland. The prior section likely attributed generic X Corp. patent-defense counsel from unrelated matters. That section should be corrected before the memo is finalized.

I'd also note one discrepancy in the prior "Key legal developments" section worth reconciling with the new search results: Law360 reports that the district court granted a stay on February 14, 2025 pending the IPR, and one docket aggregator lists this case's status as "Closed." The earlier section described the stay outcome as unknown. The IPR schedule also appears to have run on a different clock than the prior section assumed (petition filed December 12, 2024 per Docket Alarm; trial instituted June 10, 2025; oral argument orders issued Feb. 2026; one reported "Petitioner's Reply to Patent Owner's Response" deadline in December 2027). These dates should be verified against PACER/PTAB before publication.
