Contour Products Seeks Declaratory Judgment on Pillow Solve Knee-Pillow Patent.

The complaint

The case is Contour Products, Inc. v. Pillow Solve Inc., No. 3:26-cv-00770 (W.D.N.C., Charlotte Division), filed September 25, 2026, ECF No. 1 (14 pages), with a jury demand. The docket shows the case assigned to Senior Judge Frank D. Whitney. Contour seeks declaratory judgments of noninfringement and invalidity of U.S. Patent 10,143,311 and pleads tortious interference with contract and with prospective economic advantage.

What the patent covers

U.S. Patent 10,143,311, titled Knee Pillow, issued December 4, 2018, and names Pillow Solve Inc. as assignee. Claim 1 covers a knee cushion for use between the legs in a side-sleeping position, with a first region that spans the thigh portion and spaces the legs, a narrower second region that extends lengthwise across the epicondyle portion with a continuously variable thickness substantially reduced from the first region's and a compressibility suited to supporting the medial epicondyle bones without displacing the patella, and an attachment that holds the cushion on one leg. Contour seeks declarations about the Contour Legacy Knee Pillow with removable strap. (U.S. Patent 10,143,311 claim 1; Compl. paras. 2, 25 to 28.)

What the lawsuit alleges

Contour alleges, on information and belief, that Pillow Solve is a Canadian corporation and the assignee of record of the '311 Patent, and that it submitted, or caused to be submitted, a patent complaint through Amazon's patent-reporting procedures identifying the Contour Legacy Knee Pillow with removable strap. Contour alleges that Amazon removed its U.S. listings for the product, froze its inventory, and scheduled the inventory for disposal. Count I seeks a declaration of noninfringement, arguing the product lacks the claimed second-region thickness limitation. Count II alleges, on information and belief, that claims 1 to 20 are invalid for lack of written description under 35 U.S.C. 112(a) and for new matter under 35 U.S.C. 132(a), pointing to wording it says was added by amendment on November 8, 2017. Counts III and IV plead tortious interference with contract and with prospective economic advantage. (Compl. paras. 2 to 15, 28 to 70.)

The answer

The docket shows Pillow Solve's answer and counterclaim filed October 22, 2026 (ECF No. 5), followed by a corporate disclosure statement and a pro hac vice order.

What to watch next

Watch for Contour's response to the counterclaim and the initial attorneys' conference and scheduling under the court's initial scheduling order.
