Peter Pereira is a member of the Intellectual Property Litigation team in Kirkland’s London office. He has a broad practice across all aspects of IP litigation but has particular expertise in patent litigation at both trial and appellate level.

Peter’s litigation experience covers a broad range of technical fields including engineering, telecommunications and life sciences. He has significant experience acting as coordinating counsel for multijurisdictional matters, assisting clients to develop and implement their patent litigation strategies.

Peter’s recent cases include:

  • AutoStore v Ocado [2021] EWCA Civ 1003 — successfully represented AutoStore at first instance and on appeal to overturn an ex parte injunction which had been granted, restraining AutoStore from referring to certain material in ongoing International Trade Commission (ITC) proceedings. The case involved an examination of the relevant law to apply to multi-national settlement discussions and the scope of without prejudice privilege. This case is part of much broader, ongoing patent litigation between the parties, including infringement and entitlement cases brought by AutoStore in the UK High Court.
  • Sisvel v Xiaomi [2021] EWHC 1048 (Pat) — successfully defended Xiaomi, one of the largest smartphone manufacturers in the world, in an infringement action as part of high profile FRAND litigation concerning the LTE telecommunications standard.
  • BAT v Philip Morris — represent BAT as coordinating counsel with respect to numerous patent infringement actions in courts around Europe, including the UK High Court.

In 2019–2020, Peter was seconded to GSK’s Consumer Healthcare business, where his work included supporting GSK’s £10 billion joint venture with Pfizer on their respective consumer health businesses, negotiating licenses and handling all litigious trade mark matters.

The 2022 edition of the The Legal 500 UK describes Peter as having “expertise in SEP and FRAND litigation for international telecoms and technology clients”. Peter has “high expertise, excellent work commitment, dedication to case, [and is] prepared to consider novel approaches to achieve practical goals”.

In 2020, Peter was the joint winner of the AIPPI UK study prize for his submission on the topic of descriptive use as a defense in trade mark proceedings.

In 2017, Peter was a finalist in the 30 under 30 award for intellectual property by Lawyers Weekly Australia. In the same year he was part of a team which won the Best Team award at the Online Courts Hackathon in London.

In 2012–2013, Peter spent 18 months as a judicial clerk to a judge of the Supreme Court of New South Wales. Prior to joining Kirkland, he was an IP lawyer at the leading Australian firm Gilbert + Tobin.
