Buffalo Games v. SimplyTech Electronics: LCD Drawing Board Patent Dismissed With Prejudice
Buffalo Games, LLC filed suit against SimplyTech Electronics, Inc. in the Southern District of New York alleging infringement of US9927672B2, a patent covering LCD drawing board technology used in products like the Boogie Board and Doodle Pad. The case ended in a voluntary dismissal with prejudice just 54 days after filing — before the defendant had filed any answer.
Swift exit: Buffalo Games drops LCD drawing board suit with prejudice
On May 30, 2025, Buffalo Games, LLC filed a patent infringement action against SimplyTech Electronics, Inc. in the U.S. District Court for the Southern District of New York (Case No. 1:25-cv-04545), before Judge Lewis J. Liman. The suit centred on US9927672B2, a patent covering LCD drawing board technology, and named SimplyTech’s competing products as allegedly infringing the Boogie Board and Doodle Pad product lines.
The case closed on July 23, 2025 — just 54 days after filing — when Buffalo Games filed a notice of voluntary dismissal with prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i). Because SimplyTech had not yet served an answer or a motion for summary judgment, no court order was required to effect the dismissal. The with-prejudice designation means Buffalo Games is permanently barred from bringing the same infringement claims against SimplyTech on this patent in federal court.
The speed of resolution — under two months, with no substantive pleadings from the defendant — is consistent with a pre-litigation settlement, licence agreement, or a commercial resolution reached shortly after the complaint was served. The public record does not disclose settlement terms, royalty arrangements, or whether SimplyTech modified or withdrew the accused products. The absence of defence counsel on record further suggests the dispute was resolved bilaterally before formal litigation posturing began.

Resolved in 54 days — well below the median district court patent case duration of 2+ years
Dismissed with prejudice: what Rule 41(a)(1)(A)(i) means for both parties
Rule 41(a)(1)(A)(i) dismissal: unilateral and self-executing
Under Fed. R. Civ. P. 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the defendant has served an answer or a motion for summary judgment. Buffalo Games invoked this mechanism, confirming SimplyTech had served neither. The dismissal took effect upon filing — no judicial approval was required or sought.
Self-executing — no court order neededWith prejudice bars Buffalo Games from refiling these claims
A dismissal with prejudice operates as an adjudication on the merits, permanently extinguishing Buffalo Games’ right to assert the same infringement claims against SimplyTech based on US9927672B2 in federal court. Unlike a dismissal without prejudice — which preserves the right to refile — this designation provides SimplyTech with a permanent shield against this specific action. Buffalo Games voluntarily accepted this finality, strongly suggesting the underlying dispute has been resolved.
Permanent bar on refiling these claimsBuffalo Games obtains closure — but sacrifices future enforcement rights
By choosing a with-prejudice dismissal, Buffalo Games signalled confidence that whatever outcome was achieved off the record — likely a settlement, licence, or product withdrawal — adequately addressed its commercial concerns. However, the quid pro quo is permanent: should SimplyTech resume or expand the accused product line in the future, Buffalo Games cannot relitigate on US9927672B2 under this docket.
Likely resolved commercially off-recordSimplyTech exits without admitting infringement or incurring a judgment
SimplyTech Electronics avoided any merits adjudication, public infringement finding, or damages award. The absence of defence counsel on record and the rapid 54-day resolution suggests SimplyTech engaged constructively — or was simply unresponsive — and that the matter concluded before formal litigation costs escalated. SimplyTech also benefits from the with-prejudice bar, which provides permanent protection from this specific claim.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) with precision, confirming two threshold facts: SimplyTech had not answered, and no summary judgment motion had been served. Buffalo Games’ explicit election of ‘with prejudice’ — beyond the default without-prejudice presumption at this stage — is legally significant. It transforms the dismissal into a merits adjudication, extinguishing the cause of action entirely. The phrasing is consistent with a negotiated exit rather than a unilateral decision to abandon the claim, though the public record does not confirm the existence or terms of any agreement.
US9927672B2 — LCD writing tablet and eWriter drawing board technology
US9927672B2 (application number US14/971094) covers technology underlying LCD-based drawing and writing tablets — devices in which pressure applied by a stylus or finger creates visible markings on a liquid crystal display substrate without a power source for image creation. The Boogie Board and Doodle Pad product lines represent the commercial embodiment asserted in this case. This class of technology spans consumer, educational, and office-note-taking applications.
The strategic significance of US9927672B2 lies in its positioning across the consumer electronics and toy-games intersection — a space populated by low-cost imported alternatives that frequently attract enforcement attention. Buffalo Games’ willingness to file in the S.D.N.Y. against an electronics distributor signals active portfolio monetisation. For competitors sourcing or distributing similar LCD writing tablets, this patent represents a credible infringement risk that warrants proactive clearance analysis.
Should you run an FTO analysis against US9927672B2?
If your company manufactures, imports, or distributes LCD drawing boards, eWriters, pressure-sensitive writing tablets, or similar stylus-driven display products, US9927672B2 should be on your FTO radar. This case demonstrates that Buffalo Games is prepared to litigate in federal court and has counsel experienced in rapid enforcement. The product categories at issue — LCD writing tablets sold under consumer brand names — overlap with a broad range of SKUs carried by electronics distributors and toy retailers.

What this case signals for the LCD display and consumer electronics IP landscape
Rapid with-prejudice dismissals in district court often signal licensing activity or commercial settlement — with implications for the broader patent landscape.
Pre-answer dismissals are a hallmark of rapid licensing or settlement
When a patent plaintiff voluntarily dismisses with prejudice before the defendant files an answer, it typically signals a swift commercial resolution — licence grant, product modification, or a lump-sum payment. For competitors in the LCD drawing board space, this pattern suggests Buffalo Games is actively enforcing US9927672B2 and willing to litigate to compel engagement.
US9927672B2 remains active and enforceable against third parties
The dismissal resolves claims only against SimplyTech. The patent itself is unaffected — it was neither invalidated nor disclaimed. Any other manufacturer or distributor of competing LCD drawing board or eWriter products remains exposed to infringement claims. Companies commercialising similar stylus-driven LCD display technology should assess their FTO position now.

Buffalo Games filed a patent infringement complaint against SimplyTech Electronics in the S.D.N.Y. on May 30, 2025, asserting US9927672B2 covering LCD drawing board technology. The case was voluntarily dismissed with prejudice by Buffalo Games on July 23, 2025 — 54 days after filing — before SimplyTech served any answer or motion.
A Rule 41(a)(1)(A)(i) dismissal with prejudice permanently bars Buffalo Games from bringing the same infringement claims against SimplyTech Electronics based on US9927672B2. Unlike a without-prejudice dismissal, this operates as a final adjudication on the merits of the claim, foreclosing any future refiling against SimplyTech on the same patent.
US9927672B2 (application US14/971094) is a patent held by Buffalo Games covering LCD-based pressure-sensitive drawing and writing tablet technology — the type used in the Boogie Board and Doodle Pad product lines. It covers the mechanism by which stylus pressure creates visible markings on an LCD substrate, applicable to consumer, educational, and office note-taking products.
The public record does not disclose the reason. However, a voluntary dismissal with prejudice filed before the defendant has answered is consistent with a private settlement, licence agreement, or product withdrawal negotiated off the court record. The 54-day timeline and absence of defence counsel filings suggest the parties reached a commercial resolution promptly after the complaint was served.
No. The dismissal resolves only the claims between Buffalo Games and SimplyTech Electronics. US9927672B2 remains in force and is fully enforceable against other parties. The patent was not challenged, invalidated, or disclaimed in this proceeding. Companies making or selling competing LCD drawing board products remain exposed to infringement claims under this patent.
