On Thursday, December 13, 2018, BDL secured a victory for its clients Ultraproof, Inc. and Endliss Technology Inc., leading suppliers of mobile device accessories, in a patent lawsuit initiated by Spigen Korea Co. Ltd.  The lawsuit, brought by Spigen in the United States District Court for the Central District of California, asserted infringement of five patents against our clients – four design patents and one utility patent – all for mobile phone cases.  In addition to arguing non-infringement of the patents, BDL asserted counterclaims seeking to invalidate all five of the asserted patents.  BDL ultimately moved for summary judgment on the invalidity counterclaims, and the Court ruled in our client’s favor, finding all four of the design patents and the asserted claims of the utility patent invalid.[1]  This, in turn, mooted the infringement claims brought against our clients and protected them from damages exposure and a potential injunction.

Case: Spigen Korea Co., Ltd. v. Lijun Liu et al., Case No. CV 16-1985-DOC (DFMx)

Patents: U.S. Patent Nos. 9,049,283; D771,607; D753,099; D775,620; D776,648

[1] The utility claims were previously found invalid in Spigen Korea Co., Ltd. v. iSpeaker Co., Ltd. et al, 2:16-cv-8559-DOC (DFMx), which is pending appeal.
