1 case as defendant.
Vampire Labs LLC is a privately held entity founded in Austin, Texas, in 2008. The company describes itself as a developer of advanced power management technology focused on eliminating "Vampire Energy Loss," with issued patents covering technology for mobile device battery chargers and microprocessor cores using thread-level power gating. While they mention a "Vampire Proof Charger" product on their website, the broader context of their activities points to significant involvement in patent licensing and assertion.
Vampire Labs LLC operates primarily as a Non-Practicing Entity (NPE), also known as a patent assertion entity, specializing in patents related to wireless power transfer technology, particularly those compliant with the Qi Specification. The company's patent litigation posture is notably assertive, evidenced by two plaintiff cases and one defendant case in the database. Both plaintiff cases, filed in the patentee-friendly Western District of Texas, involved allegations of patent infringement against major technology companies.
Notable tracked cases include Vampire Labs LLC v. Anker Innovations Ltd and Vampire Labs LLC v. Apple Inc., both filed in the Western District of Texas on November 12, 2024. These cases asserted patents, including U.S. Patent No. 8,358,103 and U.S. Patent No. 8,575,917, related to inductive wireless charging technology. Both suits were concluded through joint stipulations of dismissal with prejudice on January 8, 2026, indicating settlements were reached. Additionally, Apple Inc. initiated a defensive action against Vampire Labs LLC at the Patent Trial and Appeal Board (PTAB) on June 27, 2025, likely challenging the validity of one of the asserted patents.
An inter partes review initiated by Apple Inc. against Vampire Labs LLC concerning patent 8358103 at the Patent Trial and Appeal Board, which was terminated as settled.
