Electronics & Semiconductors

We represent electronics and semiconductor clients of all sizes, in all matters.

Our clients include semiconductor chip and equipment manufacturers, circuit designers, chip packaging companies, leaders in the microelectronics and nanotechnology industries, medical device companies, communication systems companies, network equipment manufacturers, mobile phone manufacturers, and manufacturers of personal computer systems, to name but a few. Our services encompass extensive due diligence, patent drafting and prosecution, patent portfolio development, counseling on adversarial matters (e.g., infringement and validity analyses), trademarks, technology licensing, and litigation.

However, we are more than legal advisors. We are business allies. Our intimate knowledge of the electronics and semiconductor landscape gives us insight into the forces that shape the industry. Using that knowledge, we are able to craft solutions tailored to our clients’ specific challenges and opportunities. And because we possess more than a mere academic or technical understanding of patent issues, we can anticipate the impact of these issues on a client’s bottom line.

We are also experienced patent prosecutors with an impressive record in matters ranging from reexamination of patents to appealing PTO rejections to creating patent portfolios. In addition, we also have assisted clients in the areas of product development, licensing, and other matters that have contributed favorably to their long-term success.

When litigation is required, we stand more than ready. Our team of seasoned litigators is well-versed in the complexities of electronics and semiconductor technology, giving them the ability to quickly identify salient points and creating winning strategies. Many of our attorneys hold advanced technical degrees, have served as clerks at the District and Federal Circuit Court levels, and regularly handle cases in all districts where patent cases are filed. In addition to appearing before U.S courts, we also represent our clients’ interests worldwide, working with our foreign colleagues to enforce and protect our clients’ complex IP assets wherever, whenever the need arises

We obtained a jury verdict and a final judgment including a permanent injunction and damages of $4.5 million against Serve Global d/b/a SourceVista.com and Dharmesh Shah. At trial, mophie asserted copyright, trade dress and trademark infringement arising from the sale of counterfeit battery cases. The jury awarded damages for copyright infringement of mophie's packaging and user manual and infringement of mophie's juice pack plus® trademark. The jury also found mophie's juice pack® and juice pack pro® trademarks as well as trade dress in its packaging were infringed, while additionally finding for mophie on its claim of unfair competition.

Typhoon Touch Technologies, Inc. v. Dell Inc. et al

Typhoon filed suit against our client, Toshiba, and other leading laptop and cell phone manufacturers, alleging that their touchscreen devices infringed two patents. After we obtained a District Court judgment of no infringement, the Federal Circuit affirmed. Because the patents-in-suit had been asserted against essentially any device with a touchscreen, the decision was significant because it removed a major obstacle in the market.

Commonwealth Scientific and Industrial Research Organization (CSIRO) v. Toshiba America Information Systems, Inc.

CSIRO sued our client, Toshiba, and other leading laptop, desktop and wireless product manufacturers, alleging that their products that comply with the IEEE 802.11a, g or n standards infringed its patent. Previously, one company had been found to infringe the patent and was subject to a permanent injunction. In conjunction with the other defendants, the defense group was able to successfully settle the case after the fourth day of trial when the invalidity defense was presented to the jury.

Computer Docking Station Corp. v. Dell Inc. et al.

Non-practicing entity Computer Docking Station sued our client, Toshiba, and other leading computer makers, alleging that their products infringed a patent that related to computer docking technology. Though other defendants settled the case, we obtained summary judgment of non-infringement, successfully arguing that the patent-in-suit did not cover docking stations and docking connectors for use with laptop computers. We subsequently obtained affirmance of the judgment by the Federal Circuit on appeal.
