Blank Rome LLP

Blank Rome’s IP practice covers every aspect of national and international patent, trademark and copyright law. Our attorneys are dedicated to helping clients develop, protect, strategically manage and maximise the value of their intellectual assets.

Our IP team includes a team of 35+ dedicated patent attorneys located across the country. Our attorneys are all registered to practise before the US Patent and Trademark Office (USPTO) and are active in industries such as chemicals, medical devices, artificial intelligence, computer hardware and software, data processing, telecommunications, biotechnology and bioscience, pharmaceuticals, manufacturing, semiconductors, internet technology, energy and petroleum services, aerospace and transportation, fibre optics, media and publishing, and financial services.

Patent litigation

We have extensive experience litigating every aspect of US and international patent cases. With home offices in California, Delaware, Texas and Washington DC, we regularly appear in district courts in top jurisdictions across the country and have successfully represented clients in patent disputes with hundreds of millions of dollars on the line. We also regularly appear before the Patent Trial and Appeal Board (PTAB), the Court of Federal Claims and the Court of Appeals for the Federal Circuit. We have appeared in numerous infringement suits and declaratory judgment actions, representing both patentee and accused infringers.

At the forefront of contested proceedings before the USPTO, we have filed more than 100 petitions for inter partes reviews, post-grant reviews and covered business method patent review.

Blank Rome has a concentration in representing clients before the Court of Federal Claims, a national court in Washington DC that hears cases concerning monetary claims against the federal government. Because of our strong government contracts practice, we act for numerous companies that serve the government and sometimes seek to challenge procurement decisions on IP grounds. In addition, we leverage our strengths in appellate advocacy to defend or challenge lower court holdings in the Court of Appeals for the Federal Circuit.

Patent prosecution

We represent clients in every phase of the patent application process, from initial consultations with the inventor and prior-art searches through drafting of the specifications and claims; filing of the application; meeting with the patent examiner; responding to USPTO actions and, if necessary, appealing such actions before the PTAB; and enforcing or defending infringement claims.

We file approximately 1,600 US and foreign patent applications each year and manage more than 28,000 active patent applications for 1,500+ clients.

In addition to traditional patent prosecution services, we help clients develop their own invention disclosure processes and incentive programmes to encourage inventorship and protect inventions with increased patent filings. Members of the team routinely visit client sites to present new or changing patent prosecution rules and to provide input during patent strategy meetings.


Our patent team works with our market-leading government contracts team on patent transactional matters. Many of the government contracts we work on involve billions of dollars, with much of the value of those deals tied up in sensitive intellectual property.

We also provide legal counsel concerning a broad range of issues involving IP monetisation; licensing contracts and agreements; university tech transfer; due diligence for complex business transactions; antitrust; trade secrets; cybersecurity; and insurance coverage.
