The LED technology patent holder continues its litigation campaign


LedComm, LLC is a Dallas, TX based company that owns several patents relating to LED technology. Some of the patents currently owned by LedComm were previously assigned to Japanese electronics company Sharp.  On Monday July 19, the company filed a patent infringement lawsuit against Westinghouse Lighting Corporation alleging many counts of patent infringement.

LedComm is considered a Non-Practicing Entity (NPE) as they do not manufacture LED products, but seek to license their technology and protect their intellectual property. Over the last 18 months, LedComm has sued a variety of companies that make and sell electronics products including:

  • Sengled Optoelectronics Co.
  • Westinghouse Lighting Corporation
  • Signify North America Corporation
  • Walmart Inc.
  • Lowe's Companies, Inc
  • The Home Depot Inc.
  • TP-LINK Technologies Co., Ltd.
  • Anker Innovations Limited

The Plaintiff asserts several different patents that are allegedly violated by various Westinghouse products. The claims relate to the methods utilized with LED chips and packages in multiple products.
