Jones Day

With its extensive international network of offices, Jones Day is an excellent choice for multi-jurisdictional disputes. The US practice is well versed in litigation in the country's most significant forums, including the PTAB, especially in inter partes review proceedings, the ITC and the Federal Circuit.

The partner promotions of Sarah Geers (New York) and Thomas Ritchie (Chicago) and the departure of John Kinton to an in-house position at Walmart rang in a year of changes that continued with the departure of Christopher Harnett to Maynard, Cooper & Gale, P.C. in February 2020, the August 2020 departure of Pablo Hendler to Potomac Law Group and the departure of Ognian Shentov to launch a business.

Joe Re was a fantastic lead litigation counsel. He is especially skilled at both trial and appellate matters. He is experienced in representing both holders and alleged infringers of patents at trial and on appeal across a range of venues throughout the US. Multiple parties were in the case and Joe was always clearly the best litigator in the room so much so that the other party’s outside counsel would comment on that fact as well.

Salima Merani is hands down simply one of the best outside counsel I’ve ever worked with. Her client management skills are top notch. She not only has a command of patent law, but also of transactions/negotiations, and the business knowledge and acumen to go along.

Steve Larson is dedicated, responsive, very knowledgeable, and resourceful.

Milbank can look back on another successful year of life sciences litigation.

The IP team at Schiff Hardin is exceptionally experienced and provides litigation strategy counseling and implementation that aligns with our objectives and budget for a particular matter.

What separates Schiff Hardin’s IP team, and particularly Imron Aly, from other firms is the high level of client engagement and the focus on maximizing value for the client in achieving successful outcomes

Schiff Hardin’s team is highly professional, has a very good understanding of and experience in pharma IP Hatch-Waxman litigation. Their technical and legal skills are their strength, which they keep updated and advanced through their work and success rate. Their key capability is the strategy they suggest to get the best out of the suit for their clients. They are trustworthy and very easy to work with.

Schiff Hardin’s IP practice group has the right amalgamation of chemistry and formulation experts, along with the legal skills and expertise. They provide joint representation options and suggest cost-saving methods and are open to provide alternative fee arrangements.

I have worked with Imron Aly of Schiff Hardin and I find him extremely sharp and up-to-date and well-versed with Hatch-Waxman litigation. He is very good in prior art search and suggesting invalidation strategy for NCE/Product patents. He is good at challenging patents through inter partes review (IPR). His skills in suggesting favorable clauses in settlement agreements are very appreciable.

Schiff Hardin features a group of incredible patent litigators who carefully balance efficiency and business considerations with providing sound legal advice.

Schiff’s litigation team is highly diverse, and they have been using billing and tracking technologies to help budget matters in a highly accurate fashion.

Imron Aly is an exceptional first chair trial lawyer who still can involve himself in the ongoing litigation of his cases – that’s rare in the current profession.

Imron Aly is very passionate about his work & very proactive.

A very experienced and attentive trial team for a patent litigation. This team appreciates the complexity of patent strategy and the importance of how intellectual property fits into the larger product and business lifecycle.

The firm has been exceptional in collaborating within my legal team to help with billing, payments, and forecasted costs. In addition, Schiff places a high value on important initiatives such as diversity which are also a focal point for us.

Imron Aly is one of the most skilled trial lawyers. He brings a level of tenacity and enthusiasm which not only motivates his team, but also signals to the opponent we are prepared for trial. Imron has decades of experience and is very diligent about responding to clients and making himself available at anytime rather than delegating to his team at every turn.

‘I’m impressed with their top-down broad capabilities. The depth of their bench is impressive as well as the wide spectrum of experience that the firm has.’

I’ve been impressed with how attorneys in the firm interact and get to know the client in order to come to the right outcome.

‘I have always appreciated Jason Hoffman’s thoroughness and ability to ask the right questions. I have seen him in action in court and depositions and have always come out impressed with his preparation.’

‘Baker has uniquely talented litigators who have experiences in all forums ranging from district Courts, the ITC, the PTAB and the Federal Circuit. It is these experiences that allows Baker to leverage the right attorneys for a particular engagement and sets it apart from other firms.’

‘Jason Hoffman is an outstanding litigator at Baker & Hostetler. He immerses himself not only in the case to fully understand the issues, but also the business objective of the clients. Most attorneys don’t focus on the business objectives and thus, potentially waste valuable resources and time for a client. Jason is able to decipher complicated issues for my internal stakeholders to understand, which helps me to guide the stakeholders in the right direction for the company. ’

‘Baker Hostetler just gets it. Having worked with different firms I have always felt that Baker Hostetler understands us best and is most willing to consider different options with us as opposed to just going through the motions. Baker Hostetler’s understanding of our industry and how we work together has made them my go-to for patent litigation and general IP advice.’

‘In addition to his expert legal knowledge, Michael Anderson understands the often complicated industry in which we operate. He gives quick and practical advice and is willing to think outside of the box (suggesting various strategies and alternative ways of approaching an issue that are not always obvious). Michael makes a point of understanding our strategic goals.’
