CAMBRIDGE, Mass., Oct. 12 -- E Ink Corporation, the leading provider of electronic paper display technology, today announced that it has received its 100th utility patent from the United States Patent Office. E Ink has been awarded 24 new U.S. patents so far in 2006, almost double the number it received in 2005. The company's 100th patent describes important control hardware and software for addressing bistable displays. Bistable displays are able to maintain an image without any battery or external power source. E Ink has a growing family of patents in the area of bistable display operation, including methods to increase lifetime, improve performance and decrease system cost. E Ink's patent portfolio provides the company with broad protection for its innovative electrophoretic display technology. The company's issued patents cover topics including methods for manufacturing of the electronic ink material, processes for assembling finished displays, and techniques for integrating electronic paper displays in to finished products. While many of E Ink's patents are focused on electronic paper, many also have broader applicability in fields like organic electronics and flexible semiconductor manufacturing. E Ink has recently been awarded claims on techniques to print semiconductor particle films, pattern organic semiconductors and produce organic dielectric films at low temperatures. With over 100 additional patent applications pending, E Ink anticipates the pace of new patent issuance to continue to increase. The company has also received and applied for international equivalents of many of its U.S. patents.
