Patent Prosecution

Knobbe Martens has a reputation of developing and securing vital patent assets for our clients. We don’t just go through the motions of patent prosecution. We actively develop patent portfolios to achieve our clients’ strategic goals, whether they are focused on defensive coverage, licensing revenue, creating barriers to market entry, preparation for litigation, monetizing non-essential patent assets, or building value for a strategic exit. We have extensive experience in leading and defending due diligence, preparing patent opinions, and negotiating high-stakes patent deals. As a leader among IP firms, we participate in Patent Office pilot programs to assist the USPTO in developing new processes and programs that benefit our clients. By thinking outside of the box, we stress creative and proactive approaches to accelerating and improving prosecution results, often meeting face-to-face with U.S. Patent Examiners.

Our attorneys have strong technical and scientific backgrounds that enable us to deeply understand the details of our clients’ technologies, which allow us to craft an individualized patent strategy for each client. Many of our attorneys have doctoral or masters degrees, and many have years of industry experience prior to becoming an attorney.

Realizing the dynamic nature of patent law, we have created a number of cross-functional teams where patent prosecution and litigation attorneys work closely with each other, crafting multi-dimensional tactics and strategies that take into account our clients’ business goals. These hybrid teams are able to create stronger patents in the patent office that lead to better litigation results as well as greater insight into defending against patent lawsuits. The hybrid teams also play an essential role in representing our clients in the new post-grant proceedings instituted under the America Invents Act (AIA). Our teams of litigators and patent prosecutors work synergistically to develop strategies to navigate these quasi-litigation proceedings before the U.S. Patent Office – either to defend a client from an invalidity challenge of its patent or to develop a strategy for challenging a competitor’s patent.

We strive to understand the business realities surrounding the intellectual property. This holistic view of the legal landscape, our clients’ interests and overall industry trends give us a greater understanding of how inventions are implemented and used, as well as the direction technology itself is headed.

With the insight gleaned, we are able to quickly develop successful technology protection strategies, identify potential risks to avoid third-party action, conduct diligence associated with acquisitions, and create prosecution portfolio management strategies tailored around individual exit plans.

Journée Lighting Inc.

Our client Journée Lighting Inc. designs and manufactures state-of-the-art LED lighting fixtures. Journée Lighting invented a new light bulb that makes LED lights easier to use. The new light bulb, if never turned off, would last for 5.7 years at a fraction of the cost of a standard light bulb. GE Lumination purchased the next-generation LED module technology from Journée Lighting. A team of Knobbe Martens attorneys played an instrumental role in obtaining patent protection for the invention and providing agreement services leading to highly successful negotiations.

Kyoto University

Knobbe Martens worked closely with Professor Yamanaka and his team to obtain U.S. Patent No. 8,048,999, the first patentgranted for the work which led to Professor Yamanaka's Nobel Prize. The patent relates to a nuclear programming factor for the production of these induced pluripotent stem cells from adult cells. It is expected that the production of induced pluripotent stem cells will ultimately lead to treatments that allow the complete regeneration of injured and diseased tissues.

Knobbe Martens continues to represent Kyoto University in connection with its ongoing efforts to obtain patent protection in the United States for Professor Yamanaka's further work. We are greatly honored that Kyoto University entrusted Knobbe Martens to assist it in connection with such groundbreaking work, and we particularly appreciate the opportunity to work with Professor Yamanaka, a scientist of such renowned stature.

Specialized Bicycle: Horst Link Bicycle Suspension

Knobbe Martens was instrumental in securing patent protection on one of mountain biking's most fundamental suspension designs, the Horst Link Four Bar Suspension. After other law firms were unable to convince the U.S. Patent Office as to the patentability of the Horst Link suspension, Knobbe Martens was successful in securing three patents for the technology. The Horst Link patents became one of the cornerstones of Specialized Bicycle’s intellectual property portfolio.
