Patent Law & Prosecution

Our Work
Winthrop & Weinstine’s patent attorneys partner with our clients to develop a deep knowledge of the client’s business, products and markets to ensure that the client’s portfolio of patents and applications matches the client’s business needs. We strive to identify inventions that will help our client execute a successful business plan. We aim to secure patents that withstand the pressure of diligence inquiries and litigation, and that have real value as business assets.

Our patent attorneys work hard to develop a thorough understanding of the technology relevant to your business. Additionally, our team of patent lawyers have advanced and undergraduate degrees in electrical engineering; computer engineering; computer science; aerospace engineering; civil engineering; biochemistry; biology; public health; and molecular, cellular, and developmental biology and genetics.

Before joining Winthrop & Weinstine, many of our patent attorneys worked in private industry, which gives them first-hand knowledge of the pressures and challenges of running an enterprise.

Our patent law attorneys focus on all facets of technological innovation. Not just prosecution of patents but also patent litigation, due diligence, mergers and acquisitions. We aim to understand each invention through the eyes of both the inventor and the business that it supports. A patent must be both technically sound and relevant from a business standpoint in order to have genuine value.

The patent prosecution attorneys here at Winthrop excel in patent law and see first-hand the pressures and arguments that patents must withstand in litigation. These insights are immensely valuable to the patent prosecution process, where many litigation pitfalls can be avoided in the first place.

At Winthrop, our attorneys are well-known in the legal industry for our depth of experience and knowledge and are often sought after for leading courses and teaching patent law and litigation skills to other attorneys.
