BWB Co. v. Alibaba: Four-Patent Commercial Transaction Suit Dismissed With Prejudice
BWB Co., Ltd. asserted four U.S. patents covering commercial transaction systems and administration servers against Alibaba in the Northern District of California. After 660 days of litigation, the court entered judgment in favor of Alibaba with prejudice — foreclosing any refiling of the same claims.
Four-Patent E-Commerce Transaction Suit Against Alibaba Ends in Defense Win
BWB Co., Ltd., a company asserting rights in commercial transaction system technology, filed suit against Alibaba Group (US) Inc. and related entities on November 15, 2023 in the U.S. District Court for the Northern District of California before Judge James Donato. The complaint alleged infringement of four U.S. patents — US10460366B2, US11776027B2, US11138644B2, and US11776028B2 — each directed to commercial transaction systems, administration servers, and related software programs.
The case closed on September 5, 2025 following a second order of dismissal with prejudice at docket entry 45, with judgment formally entered under Federal Rule of Civil Procedure 58 in favor of Alibaba. A dismissal with prejudice constitutes an adjudication on the merits, meaning BWB Co. is barred from reasserting the same patent claims against Alibaba in a new action — a materially stronger outcome for the defendant than a without-prejudice dismissal.
The 660-day duration and the presence of a ‘second order of dismissal’ suggests the case navigated at least one prior procedural hurdle before final termination, though the public record does not disclose settlement terms or whether the dismissal was consent-based or court-imposed. The involvement of Simpson Thacher Bartlett defending Alibaba signals the dispute was treated seriously, while BWB’s use of Blakely Law Group and YK Law LLP is consistent with a licensing-focused enforcement strategy.

Dismissed with prejudice: what the judgment in Alibaba’s favor means
Dismissal with prejudice bars all future re-filing of these claims
A dismissal with prejudice under Rule 58 constitutes a final judgment on the merits. Unlike a without-prejudice dismissal, BWB Co. cannot refile the same four patent infringement claims against Alibaba in any federal court. The reference to a ‘second order of dismissal’ in the docket suggests an earlier procedural dismissal was followed by an amended complaint or cure opportunity before the final with-prejudice termination.
Final judgment on the meritsBWB loses enforcement rights against Alibaba permanently
For BWB Co., the with-prejudice judgment forecloses this specific enforcement avenue against Alibaba entirely. The patents themselves remain in force and could theoretically be asserted against other parties, but any damages claim or injunctive relief against Alibaba on these four patents is extinguished. The public record does not disclose whether any licensing discussions occurred or whether a settlement with distinct commercial terms underlies the dismissal.
Claims extinguished against AlibabaAlibaba secures permanent protection from these four patents
Alibaba emerges with a judgment that functions as a complete shield against re-assertion of US10460366B2, US11776027B2, US11138644B2, and US11776028B2. This outcome, defended by Simpson Thacher Bartlett, is consistent with a strategy of forcing a merits-level resolution rather than accepting a licensing arrangement. Alibaba’s commercial transaction and marketplace operations face no ongoing exposure under these specific patents.
Full defense judgment securedE-commerce platforms face continued patent risk from administration server IP
This case is consistent with a broader pattern of commercial transaction system patents being asserted against major platform operators. While the outcome here favored Alibaba, the four patents asserted by BWB remain active and could be targeted at other e-commerce, marketplace, or payment platform operators. Companies deploying comparable transaction system architectures should assess their exposure to this patent family before receiving a demand letter.

Official order — verbatim text
The verdict language — ‘judgment is entered in favor of defendants’ pursuant to Rule 58 and a second dismissal with prejudice order — is unambiguous in scope. It constitutes a final merits judgment, not a procedural or administrative closure. The ‘second order’ phrasing suggests BWB had at least one prior opportunity to cure its complaint, making the final with-prejudice termination a considered judicial determination that the claims could not be sustained. This forecloses res judicata challenges and strengthens Alibaba’s position in any future dealings with BWB over these patents.
US10460366B2 — Commercial Transaction System and Administration Server Technology
The four asserted patents — US10460366B2, US11776027B2, US11138644B2, and US11776028B2 — are directed to commercial transaction systems, administration servers, and associated software programs. The application numbers span filings from 2017 (US15/511729) through 2021 (US17/491584 and US17/491590), indicating a multi-generational patent family built around a core commercial transaction architecture. This breadth across application generations suggests a deliberate portfolio-building strategy intended to capture evolving implementations of the underlying technology.
The commercial transaction and administration server space sits at the intersection of e-commerce infrastructure, marketplace platforms, and payment processing — a domain where large operators like Alibaba deploy highly complex, proprietary system architectures. Patent families of this type are frequently used in licensing campaigns targeting platform operators, as the claim language can be drafted broadly enough to potentially read on standard marketplace workflows. The survival of these four patents post-litigation means they remain a credible assertion risk for any operator in adjacent technology spaces.
Should you run an FTO analysis against US10460366B2 and the BWB patent family?
Any company building or operating commercial transaction platforms, marketplace administration systems, or e-commerce infrastructure software should consider whether its architecture intersects with the BWB patent family. The four patents span application dates from 2017 to 2021 and cover multiple implementation layers of transaction systems. The fact that these claims survived long enough to reach a second dismissal — rather than being quickly disposed of on § 101 grounds — suggests at least some claim scope was not immediately vulnerable to an eligibility challenge.
PatSnap Eureka’s FTO Search Agent allows product and IP teams to map their transaction system architecture against the claim sets of US10460366B2, US11776027B2, US11138644B2, and US11776028B2 in minutes. Eureka surfaces family members, continuation risk, prosecution history, and prior art — enabling a defensible FTO opinion before a demand letter arrives rather than after. For platform operators in the e-commerce or marketplace infrastructure space, proactive clearance is materially cheaper than reactive litigation.

What this case signals for the e-commerce and transaction platform IP landscape
A four-patent enforcement action ending in a with-prejudice defense judgment carries clear signals for both platform operators and patent licensors in the commercial transaction space.
With-prejudice dismissals in N.D. California set strong precedent for defendants
When a plaintiff’s case is dismissed with prejudice before trial, the defendant gains a durable shield. For Alibaba, this judgment effectively ends exposure to BWB’s patent family on its U.S. operations. Other platform defendants facing similar assertion campaigns can point to this outcome when evaluating litigation versus licensing strategies.
BWB’s four-patent portfolio remains live against other commercial transaction platforms
The dismissal binds only the parties. US10460366B2 and its three co-asserted patents are not invalidated by this outcome. Any company operating commercial transaction systems, marketplace administration servers, or related software infrastructure should treat these patents as active litigation risk and conduct a targeted FTO review.
BWB v Alibaba — key questions answered
BWB Co., Ltd. filed a four-patent infringement suit against Alibaba Group (US) Inc. in the Northern District of California on November 15, 2023. The case was dismissed with prejudice on September 5, 2025, with judgment entered in favor of Alibaba under FRCP Rule 58 following a second order of dismissal at docket entry 45.
BWB asserted four patents: US10460366B2, US11776027B2, US11138644B2, and US11776028B2. All four are directed to commercial transaction systems, administration servers, and related software programs. Application filing dates span from 2017 to 2021, suggesting a deliberate multi-generational portfolio strategy.
A dismissal with prejudice is a final judgment on the merits. BWB Co. is permanently barred from refiling these same infringement claims against Alibaba. The four patents themselves remain valid and enforceable, but the specific claims against Alibaba are extinguished by res judicata. BWB may still assert these patents against different defendants.
The verdict cites a ‘second order of dismissal with prejudice’ at docket entry 45. This typically indicates that the court previously dismissed BWB’s complaint — likely without prejudice — giving the plaintiff an opportunity to amend. BWB’s inability to sustain its claims after amendment resulted in the final with-prejudice termination, suggesting fundamental deficiencies in the pleadings or claim scope.
Yes. The dismissal in BWB v. Alibaba does not invalidate the four asserted patents — it only bars BWB from suing Alibaba on those specific claims. US10460366B2 and its co-asserted patents remain active and could be asserted against other platform operators, marketplace administrators, or e-commerce infrastructure companies. A targeted FTO review is advisable for companies operating in this technology space.
