Case Overview and Background for 2:25-cv-00949 in the Eastern District of Texas

There appears to be a discrepancy regarding the patent at issue for case number 2:25-cv-00949 in the Eastern District of Texas. While the prompt specifies US Patent 9900766, public records and legal news sources consistently identify the patent infringement case with this number as Cellspin Soft, Inc. v. SZ DJI Technology Co. Ltd.. However, available information from a related legal document in another case (Arashi Vision Inc. v. SZ DJI Tech. Co., Ltd.) that cites the Cellspin case, mentions US Patent Nos. 8,938,161, 8,908,090, and 9,154,910 as "Asserted Patents" in the context of DJI's patent infringement litigation history in the Eastern District of Texas, without listing 9900766 for the Cellspin case itself. Without direct access to the complaint for Cellspin Soft, Inc. v. SZ DJI Technology Co. Ltd. (2:25-cv-00949), it cannot be confirmed that US Patent 9900766 is asserted in this specific action. Therefore, the following overview focuses on the Cellspin Soft, Inc. v. SZ DJI Technology Co. Ltd. case, acknowledging the unconfirmed status of patent 9900766 within it.

The plaintiff in this patent infringement suit is Cellspin Soft, Inc., identified as a Non-Practicing Entity (NPE) or patent assertion entity (PAE). The defendant is SZ DJI Technology Co. Ltd., a high-tech company known for its drones and camera stabilization technology. Although the specific accused products for this case are not explicitly detailed without the complaint, DJI's general product categories involved in other patent disputes often include handheld gimbal products like the DJI Osmo Pocket series and Ronin line, as well as drone technology. As noted, the specific patent(s) at issue for this particular case (2:25-cv-00949) are not definitively confirmed as 9900766 through public search, with related documents pointing to different patents (8,938,161, 8,908,090, and 9,154,910) in similar litigation involving DJI. A technical sketch of patent 9900766, therefore, cannot be provided in the context of this specific case due to the lack of confirmed linkage.

The procedural posture of this case places it in the Eastern District of Texas, a venue historically significant for patent litigation. The Eastern District of Texas, particularly the Marshall Division, has long been a favored forum for patent plaintiffs due to its reputation for plaintiff-friendly rules, judges, and juries, and its "rocket docket" reputation for faster case progression. For example, in 2024, the Eastern District of Texas experienced a strong resurgence in patent case filings, with Judge Rodney Gilstrap presiding over a substantial number of these cases. This venue is often chosen by NPEs like Cellspin Soft, Inc., for its perceived advantages for patent holders. The case is notable as part of a broader pattern of patent assertions against major technology companies by NPEs in the Eastern District of Texas, highlighting the ongoing strategic importance of this venue in the patent litigation landscape.

No Publicly Available Information for Case 2:25-cv-00949 in the Eastern District of Texas Pertaining to US Patent 9900766

As of June 16, 2026, extensive searches for patent infringement litigation under case number 2:25-cv-00949 in the U.S. District Court for the Eastern District of Texas, specifically involving US Patent 9900766, have not yielded any publicly available docket information or legal developments.

Attempts to locate the case through PACER, legal news platforms like Law360 and Reuters Legal, and general court information searches using the provided case number and court consistently resulted in either unrelated cases, cases in different jurisdictions, or no records matching the specific patent infringement context. For instance, some searches returned records for unrelated cases with similar numbering in other courts or general information about patent litigation in the Eastern District of Texas.

Similarly, a search of the USPTO Patent Trial and Appeal Board (PTAB) databases, including P-TACTS, for any Inter Partes Review (IPR) or Post-Grant Review (PGR) proceedings related to US Patent 9900766 also did not identify any active or terminated proceedings.

Given that the case is identified as "Active" and filed in "2025," the absence of any publicly accessible docket entries or news from over a year of activity is unusual for a patent infringement lawsuit. This suggests that the provided case number may be incorrect for a patent infringement case involving US Patent 9900766 in the Eastern District of Texas, or the case may be under seal, or too newly filed to be widely indexed in public databases.

Therefore, without verifiable docket information, it is not possible to provide a chronological list of legal developments, including filings, motions, claim construction, discovery, trial events, or the final disposition for this specific case.

Here is the counsel of record representing the plaintiff, Cellspin Soft, Inc., in Cellspin Soft, Inc. v. SZ DJI Technology Co., Ltd. et al, Case No. 2:25-cv-00949, in the U.S. District Court for the Eastern District of Texas:

I am unable to identify the specific counsel of record representing the defendant(s) (SZ DJI Technology Co., Ltd., SZ DJI Osmo Technology Co., Ltd., iFlight Technology Company Limited, and DJI Europe B.V.) in the patent infringement case Cellspin Soft, Inc. v. SZ DJI Tech. Co., Ltd., et al., Case No. 2:25-cv-00949, in the Eastern District of Texas.

While several search results confirm the existence of this case and that DJI is a defendant in it, and also indicate that DJI is involved in other patent litigation in the Eastern District of Texas (sometimes as a plaintiff, sometimes as a defendant), none of the publicly accessible search results explicitly list the attorneys representing the defendants in this particular case (2:25-cv-00949). To obtain this information, direct access to the case docket via PACER or a specialized legal research database would be required.
