Keeping your innovations one step ahead

It’s harder than ever to stay ahead of the competition, with waves of innovation disrupting every industry. Businesses need to take steps to protect their inventions and technologies.

Dunlap Bennett & Ludwig’s team of patent lawyers advises businesses on patent strategy and helps clients prosecute and defend utility patents and design patents. We also advise clients on patent procurement and represent clients in post-grant proceedings and litigation. Our intellectual property team has deep backgrounds in science and technology that complement their legal knowledge, giving us an insider’s perspective on how to best help our clients protect their ideas.

Our experience with patent law

Dunlap Bennett & Ludwig’s patent lawyers help our clients understand what they can protect and how they should protect it under patent law. We assist clients with the day-to-day management of patent and intellectual property portfolios and provide needed counsel in responding to client-completed patent applications. We have worked with clients to protect everything from simple mechanical inventions to complex electrical patents, chemical patents, biotechnology patents, and app software patents.

Our team handles patent applications domestically through the U.S. Patent and Trademark Office (USPTO) and internationally through the World Intellectual Property Organization (WIPO). We also help clients challenge and defend patents in trials before the Patent Trial and Appeal Board (PTAB), including in post-grant review and covered business method review proceedings.
