TWW previously sued Wal-Mart, alleging the sale of airbeds made by Bestway, Intex, and Coleman (“the Manufacturers”) containing built in air-pumps constituted infringement of its three Asserted Patents US Patent Nos. 7,246,394, 7,346,950, and 9,211,018.

  • Representing Apeks, LLC, a subsidiary of Prospiant, Inc., an innovator and market leader in the field of botanical extraction. In April 2022, the Firm filed a complaint in the ITC on Apeks’ behalf against 15 respondents on three patents related to centrifuge equipment and one patent related to falling film evaporators used for the distillation of botanical extractions. We are in the process of settling with four respondents and have moved for entry of default with respect to a number of others. Fact discovery is beginning. This matter is the first ITC investigation in the botanical extraction or CBD oil industry and represents a significant milestone in the growth and maturation of that industry. It is also Apeks’ first foray into patent litigation and its first test of its years-long focus on intellectual property.

This matter is particularly significant/complex because the patent in question was potentially going to preclude our client from business in North America. The project was extremely sensitive because it impacted immediate OEM bidding processes. The client is a manufacturer of parts that provide a market share of up to 90% of certain suspension systems in North America.
