Chiesa Shahinian & Giantomasi PC

Chiesa Shahinian & Giantomasi is highly recommended for its prosecution proficiency: one client comments, “The firm has prosecuted hundreds of patent applications for us, primarily in the area of complex software. Their attorneys work very well with inventors and always produce high-quality applications.” The group has excelled in 2018, having gained an influx of work from several of Japan’s top law firms. Co-chair of Chiesa’s IP group Jeffrey Weinick “can be trusted with your most important inventions – his work requires literally zero supervision. He is one of the most experienced and capable prosecutors around”, which explains why he works closely with prestigious clients such as AT&T, Bloomberg and Siemens.

Fox Rothschild LLP

The already steep growth trajectory of Fox Rothschild’s IP practice accelerated in 2018, as the firm expanded its southeastern footprint by acquiring mid-Atlantic law firm Smith Moore Leatherwood. Meanwhile in the Northeast, clients in the Garden State continue to enjoy the firm’s superior all-round services, which are conveniently accessible from three different New Jersey bases – Atlantic City, Morristown and Princeton. Managing the latter and spearheading the IP litigation group is microbiology PhD and veteran litigator and counsellor Gerard Norton. He is a crucial member of a large team that supports Rutgers University with international prosecution.

Gibbons PC

“The attorneys at Gibbons possess a refined understanding of their clients’ businesses and can help with any patent-related project. They are extremely easy to work with because they appreciate the commercial pressures faced by in-house lawyers and have a deep knowledge of the pharmaceutical industry.” Leading the practice and at the top of his game in life sciences litigation is David De Lorenzi, who garners brilliant market feedback: “David’s commitment, creativity and ingenuity in litigation are incredibly impressive. While positioning cases to win at trial, he maximises his advantage to secure wins outside of the courtroom – not many lawyers can do both simultaneously. While handling the most complex global matters, he provides an excellent client service at a truly reasonable price.” A distinctive feature of the firm is its pool of leading individuals with first-hand industry experience, including George Johnston and George Gould, both former chief patent counsels at Hoffmann-La Roche, and Robert Rudnick, who held roles at AT&T and various spin-offs. As a scientist and deal broker, Rudnick is highly praised: “Robert is an excellent negotiator and contract adviser. He is an inventor himself so he really understands the scope of what his clients’ scientists are doing, enabling him to assist them in developing the language to successfully pursue patent applications and thereby adding a lot of value.” Vital contributions in all areas – prosecution, litigation and transactions – come from rising star Christopher Strate, an even-keeled counsellor who debuts in the IAM Patent 1000 this year.

Greenberg Traurig LLP

Home to more than 200 patent attorneys and professionals spread across multiple offices, Greenberg Traurig is an IP powerhouse. Undertaking cutting-edge prosecution work as well as high-stakes litigation, it tackles any patent matter thrown at it. New Jersey is home to one of the set’s best prosecutors – Barry Schindler, a master portfolio builder and IP strategist. Clients love having him in the trusted adviser role, which he plays to perfection; similarly, versatile expert James DeCarlo “displays incredible dedication to his clients”. “He gets fantastic results in difficult cases at the USPTO.”

Lerner David Littenberg Krumholz & Mentlik LLP

“Lerner David is an IP firm with a global reach, a stellar client base and a well-deserved reputation for excellence.” Having mastered the arts of patent litigation, prosecution and transactions, the firm is the premier choice for a host of prestigious clients. Acquitting themselves with distinction on the litigation front are William Mentlik, Gregory Gewirtz and Roy Wepner, three trial veterans with enviable track records. Combining a full-time practice with his managing partner role for more than two decades, Mentlik has a mind like a sponge, quickly absorbing all types of information and translating it into engaging narratives. Gewirtz is technically accomplished thanks to extensive prosecution experience, and he makes it count in the courtroom. Wepner is an accomplished brief writer and recently won an appeal before the New York Supreme Court Appellate Division for New York University after a breach of contract action it brought against Pfizer was dismissed. The litigation practice was strengthened recently by the arrival of Scott Samay, a proven trial lawyer who came up at Winston & Strawn. Debuting in the IAM Patent 1000 this year, Michael Teschner is an ace up the firm’s sleeve when it comes to post-grant proceedings. He heads the chemical practice. Key pillars of the transactional team, Bruce Sales and Keith Gilman are wonderfully commercial IP strategists and risk mitigators.

Lowenstein Sandler LLP

Lowenstein Sandler conducts innovative national and international work for iconic technology companies. Key highlights for the firm include the development of a patent prosecution centre in Utah and a growing influence in California thanks to Kevin Grange and Marina Portnova respectively. In New Jersey, start-up guru Mark Kesslen maintains the firm’s status as a destination for ultra-strategic advice relating to business creation, product launch and commercial transactions; Robert Paradiso ensures this trailblazing status is maintained for prosecution and counselling services in the chemical area; and Stephen Buckingham soothes clients’ litigation headaches.

McCarter & English LLP 

With Newark headquarters and offices sprinkled all over the mid-Atlantic and Northeastern landscapes, McCarter & English is not just one of the largest and oldest full-service firms in the United States – it is a key local reference in New Jersey for IP matters. With Beverly W Lubit on deck, the firm is a discerning choice for life sciences clients in need of refined prosecution, regulatory, litigation and transactional counsel. Lubit fuses the analytical skills of a scientist with the business eye of an entrepreneur. John E Flaherty, a seasoned Hatch-Waxman Act litigator, further strengthens McCarter & English’s life sciences acumen.

Other recommended experts

Once again recommended for litigation, prosecution and transactions in this year’s edition of the IAM Patent 1000, Joel Bock at Dentons is a man of many talents. One of his clients comments, “In the 10 years we have been working with Joel, we have successfully filed and received approval on many patents, with more in the pending stage. He is a brilliant attorney and has guided us through the whole of our technical development, being instrumental in developing litigation strategies where necessary. He’s a top resource, whatever you want to do.”
