The ensemble has also diversified its capabilities to handle prosecution and transactional mandates, making it an excellent one-stop shop when it comes to patent services.

“Green Griffith spun out of a larger firm with the intention of providing a more personalised top-to-bottom service to clients, which it achieves with resounding success. It puts a profoundly experienced team on to the playing field – one with an excellent record of success in trials and appeals.  However, driven by a desire to protect rights holders and realise their long-term strategic objectives, the outfit also engages in portfolio development, due diligence, licensing and opinion work, making it an excellent one-stop shop for life sciences companies.

Chicago partners Robert Green and Christopher Griffith form a tight-knit and collaborative team, serving as sword and shield for patrons.  Veteran partner Green elevates any patent discussion and has rich strategic knowledge, having litigated many high-value drug products. Founding partner Griffith understands the pharmaceutical industry from a business perspective and takes his clients’ commercial goals to heart when litigating. These lawyers clear obstacles and make a huge impact.”

” … Green, Griffith & Associates LLP now has its full complement of leading individuals included in the IAM Patent 1000. The group’s patent litigation experience – and especially its trial seasoning – is impressive, as is its technical wherewithal: the combination has proved instrumental in numerous notable successes on behalf of top life sciences companies. The set also does much for clients away from the courtroom in counseling them at a strategic level on infringement and other matters, which makes for a well-rounded, reliable service.”

“Green, Griffith … is not trial-blinkered as a litigation boutique; it partners closely and early with clients on business strategy, giving it intimate familiarity with products and commercial objectives when disputes do flare. Those who serve in lead roles do not just show up in the courtroom, but help to put battle plans together from day one, which helps them tell better stories at trial – and ones with not a single hole in them.”

“Pharmaceutical supremo Green, Griffith … functions like an in-house advisory team; its lawyers connect with clients’ R&D folks as they formulate new products so as to become embedded in their innovation processes and business – an approach that pays off hugely at trial.”

“Each demonstrates the commitment required for top-notch trial work and they all thrive in high-pressure situations. They prepare thoroughly to put on a great case and are extremely effective at tearing into the other side’s experts and dismantling their theories.”
