VDPP, LLC v. Bullitt Mobile Limited — Image Processing Patents Dismissed Without Prejudice
VDPP, LLC asserted two image-modification patents against rugged device maker Bullitt Mobile in the Western District of Texas. After 395 days of litigation, VDPP voluntarily dismissed all claims without prejudice before Bullitt served an answer — leaving the door open for refiling.
Image patent suit exits W.D. Tex. without a merits ruling after 13 months
On August 18, 2023, VDPP, LLC filed suit against Bullitt Mobile Limited in the Western District of Texas before Judge Robert Pitman, asserting infringement of US10021380B1 and US9948922B2 — both directed to methods and systems for modifying an image. Bullitt Mobile, known for manufacturing rugged smartphones, was accused of deploying image-processing functionality that allegedly falls within the scope of VDPP’s patent claims.
On September 13, 2024, VDPP filed a notice of voluntary dismissal of all claims without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Bullitt had not yet served an answer or a motion for summary judgment, the dismissal was self-effectuating and required no court order. Judge Pitman confirmed the case was closed on September 16, 2024. The without-prejudice designation means VDPP retains the legal right to refile the same claims against Bullitt in the future.
At 395 days, the case ran notably long before a pre-answer dismissal — suggesting negotiations, licensing discussions, or strategic reassessment may have been underway. The public record does not disclose the reason for dismissal or whether any commercial arrangement was reached between the parties. The absence of a defendant law firm on record and Bullitt’s apparent non-appearance throughout the case are consistent with early-stage settlement dialogue or a decision by VDPP to reassess claim scope or venue.

Voluntarily dismissed without prejudice: what the record reveals
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit right
Under Fed. R. Civ. P. 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the opposing party serves an answer or motion for summary judgment. Because Bullitt Mobile had not responded, VDPP’s notice was self-effectuating — the case closed automatically on filing. No judicial approval or cost order was triggered.
No merits adjudicationWithout prejudice: the public record is silent on why
A dismissal without prejudice leaves the plaintiff free to refile the same claims. A dismissal with prejudice would have permanently barred VDPP from reasserting these patents against Bullitt. The Basis of Termination confirms this dismissal is without prejudice, but the public record does not disclose whether a settlement, licensing deal, or strategic decision drove the choice. Both scenarios remain plausible.
Refiling remains possibleVDPP retains full enforcement rights against Bullitt
By dismissing without prejudice, VDPP preserves the option to re-assert US10021380B1 and US9948922B2 against Bullitt Mobile in the future. No claim construction, invalidity finding, or non-infringement ruling was issued. VDPP’s patents remain in force and have not been adjudicated on the merits, meaning their enforceability against Bullitt is unchanged.
Patents still enforceableBullitt exits without prejudice — exposure not extinguished
Bullitt Mobile secured no court ruling validating its non-infringement or invalidity position. While the immediate litigation threat is removed, the without-prejudice nature means future exposure persists. Companies in the rugged mobile and image-processing space that share similar product architectures should monitor VDPP’s assertion activity and consider FTO analysis against both asserted patents.

Official order — verbatim text
The closing order confirms the dismissal was self-effectuating under Rule 41(a)(1)(A)(i) — no judicial merits assessment was conducted. The court’s citation to In re Amerijet underscores that Bullitt’s non-appearance was the operative fact: had Bullitt filed an answer, VDPP would have required either a stipulation or court order to exit. The without-prejudice designation means neither patent validity nor infringement was adjudicated, and no issue preclusion attaches to either party.
US10021380B1 & US9948922B2 — Methods and Systems for Modifying an Image
US10021380B1 (application no. US15/907614) and US9948922B2 (application no. US15/683623) both claim methods and systems for modifying an image. The patents sit within the mobile imaging and computational photography domain — covering processes by which a device captures, processes, or transforms image data. Both patents issued as granted US utility patents, and their application numbers suggest they were filed in the 2017–2018 period, placing them squarely in the generation of smartphone camera software innovation.
For device makers integrating image-processing pipelines — particularly those handling real-time modification, filtering, or enhancement — these patents represent a non-trivial assertion risk. VDPP’s decision to assert both patents together against a rugged smartphone manufacturer suggests the claims are drafted broadly enough to reach standard mobile camera or imaging workflows. Any company commercialising modify-an-image functionality on a mobile platform should treat both patents as live FTO targets until their claims are definitively narrowed or invalidated.
Should your product team run an FTO against US10021380B1 and US9948922B2?
If your team is developing or commercialising image modification, processing, or enhancement features on mobile or rugged devices, both patents asserted in this case are directly relevant. No claim construction ruling or invalidity finding emerged from this litigation, meaning the claims remain in their broadest enforceable form. Companies supplying imaging SDKs, camera app software, or image-pipeline IP to device manufacturers are equally exposed to downstream assertion risk.

What this case signals for the mobile imaging IP landscape
VDPP’s pre-answer dismissal pattern and the survival of two image-modification patents warrant close attention from mobile device makers.
Pre-answer dismissals in W.D. Tex. often precede refiling or licensing
When a plaintiff dismisses without prejudice before any substantive response, it typically signals one of three outcomes: a licensing deal was reached privately, the plaintiff is reassessing claim scope or venue, or it is building a broader enforcement campaign. All three scenarios leave the defendant and similarly situated companies exposed to continued risk.
Both image-modification patents remain active and unadjudicated
US10021380B1 and US9948922B2 have not been tested in court or at the Patent Trial and Appeal Board in this case. For product teams developing image processing pipelines for mobile or rugged devices, both patents represent live FTO considerations. No prior art or claim construction record emerged from this litigation.
VDPP v Bullitt — key questions answered
VDPP, LLC filed a patent infringement suit against Bullitt Mobile Limited in the Western District of Texas on August 18, 2023, asserting US10021380B1 and US9948922B2. On September 13, 2024, VDPP voluntarily dismissed all claims without prejudice under Rule 41(a)(1)(A)(i). The case was closed on September 16, 2024 with no merits ruling.
Dismissed without prejudice means VDPP retains the right to refile the same patent infringement claims against Bullitt Mobile in the future. No court ruling addressed patent validity or infringement. The dismissal was self-effectuating under Rule 41 because Bullitt had not yet filed an answer, meaning no court order was required to close the case.
VDPP asserted two patents: US10021380B1 (application no. US15/907614) and US9948922B2 (application no. US15/683623). Both patents cover methods and systems for modifying an image and relate to mobile imaging and image-processing technology. Neither patent was adjudicated on the merits in this case.
Yes. Because the dismissal was without prejudice, VDPP is not barred from asserting US10021380B1 and US9948922B2 against Bullitt Mobile again. No issue preclusion or claim preclusion attaches from a without-prejudice dismissal. Future refiling risk remains a live consideration for Bullitt and similarly situated rugged device manufacturers.
The public record does not disclose the reason for the dismissal. The 395-day duration before a pre-answer dismissal is longer than typical, suggesting possible settlement negotiations, licensing discussions, or a strategic decision to reassess venue or claim scope. The absence of any defendant law firm on record and Bullitt’s apparent non-appearance throughout are consistent with early-stage resolution dialogue.
