True Innovations Sues On Design Patent

On June 1, 2010, True Innovations, Inc. filed a complaint in the Northern District of California against Marco Group, Inc. (Missouri) and Zhejiang Qianglong Seating Co. (China) alleging infringement of United States Design Patent No. D494,791 entitled "Chair Arm Support" (Civil Action No. 10-cv-2499-EDL). A copy of the complaint may be found by clicking here.


The '791 patent is a good example of claiming just a portion of an item of furniture. The solid lines in the drawings define the scope of the claims. Here, the patentee True Innovations is claiming just the arm support. The support may appear on any chair and still infringe the '791 patent. A copy of the '791 patent is attached to the complaint and Fig. 1 is reproduced below:
