Maxim Integrated Products, Inc. (PINKSHEETS: MXIM) announces that it has filed a patent infringement complaint against Taiwan-based Anpec Electronics Corporation in the U.S. District Court for the Northern District of California.
In its complaint, Maxim asserts that several of Anpec's audio-related products infringe on U.S. Patent No. 7,061,327, which covers Maxim's DirectDrive technology. The complaint seeks immediate termination of the shipment of Anpec Electronics' offending products, unspecified damages, and a court-ordered injunction against future infringement by Anpec Electronics.
Maxim's DirectDrive technology provides a breakthrough in the consumer electronics market by completely eliminating the need for large and often expensive DC-blocking capacitors at the output of headphone/headset amplifiers. With the continued importance of music capabilities in mobile devices, it is believed that there are over one billion headphone amplifiers sold per year.
"Maxim's DirectDrive technology covered by the patent is an important component of the Company's focus on innovative electronics that interact with people, the physical world, power sources, and other digital systems. We intend to protect and enforce this patent vigorously," said Vijay Ullal, Group President at Maxim.
Maxim Integrated Products is a leading international supplier of quality analog and mixed-signal products for applications that require real-world signal processing.
