Office supply retailer Staples, Inc., was granted summary judgment in February in a patent infringement action brought by dbest products, Inc., over a folding office crate manufactured and sold by Staples. The case turned on whether dbest, a consumer products development company, withheld knowledge of prior art in its patent application for a folding cart with a lid similar to the lid on Staples’ “Deluxe Folding Crate.” (dbest products, Inc. v. Staples, Inc., No. 07-cv-04895 (C.D. Cal. Feb. 25, 2009)). The U.S. District Court for the Central District of California held that dbest withheld information about competing products in the marketplace when filing for its patent, undermining its claim of originality. The court invalidated dbest’s patent, finding the design for the company’s cart “obvious” in light of Staples’ patent. In its motion for summary judgment, Staples emphasized dbest’s “unmistakable intent to deceive the Patent Office” by withholding its knowledge of prior art, which sealed dbest’s fate. To borrow a phrase from the Staples advertising campaign: Winning a case when your opponent withholds prior art? That was easy!
