SJ Wang is a patent agent in the firm’s Orange County office and a member of the litigation practice. He primarily focuses his practice on U.S. and international patent prosecution and litigation support.

SJ has developed substantial practices in the area of patent prosecution and patent litigation support. His patent prosecution experience includes both U.S. and international patent applications. His patent litigation support experience includes providing technical and scientific advice and assisting with infringement/invalidity analysis.

SJ has worked with a host of technologies in connection with both litigation and patent prosecution, including computers, microprocessors, flash memories, DDR2 SDRAMs, semiconductor manufacturing processes, wireless communications, flashlights, motorcycles, mobile phones, mobile device protective cases and accessories.

Over the last thirteen years, SJ has managed and assisted with the worldwide prosecution of multiple patent portfolios comprising more than one thousand active patents and patent applications. He has prepared numerous patent applications in the areas of electrical, mechanical, and optical arts. He has also worked with attorneys to prepare claim charts for infringement analysis, perform invalidity analysis, and prepare noninfringement opinions.

From 1995 to 2001, SJ was a manager with TSMC, Hsin-Chu, Taiwan. He initiated and ran the company’s third-party design house alliance program, for which he evaluated, signed up, and managed more than 20 third-party design service companies. He also drafted, reviewed, and negotiated contracts with customers, vendors, and third-party design service companies. In addition, SJ conducted patent infringement/validity studies on potential silicon IPs and drafted legal memoranda and opinion letters. He conducted patent harvest discussions that resulted in more than 50 new patents for the company. He also worked as a staff member to the director and coordinated recruiting. On the engineering side, he coordinated and executed projects involving multiple team members in design and process porting on megacells and DSP cores.

From 1993 to 1995, SJ was with Cochran Consulting in Richardson, Texas, where he was an engineering consultant and assisted with patent infringement analysis through reverse engineering, analyzing target products (electronics systems, circuit boards, and integrated circuits such as CPUs, DSPs, SRAMs, DRAMs, flash memories, etc.) to determine their structure and/or method of operation. He identified clients’ patents practiced by target products and prepared evaluation reports for clients and exhibit materials for the courts based upon results of the foregoing patent infringement analysis.

From 1987 to 1991, SJ was with UMC, HMC, and ERSO/ITRI, all in Hsin-Chu, Taiwan, where he was a computer IC designer/section manager. He joined the 486 CPU design project with UMC. At HMC, he headed up a design team in the design of a real-time clock, direct memory access controller, interrupt controller, and universal asynchronous receiver/transmitters. At ERSO/ITRI, he redesigned a 16-bit, military standard CPU, and he designed test boards and wrote test patterns and application programs for functional testing of the CPU.
