Marks & Clerk – UK 2021

JUVE Comment

Thanks to its strong position in life sciences patents, this mixed patent firm has made good headway in the year of the coronavirus pandemic. This allowed the patent attorney branch at the Birmingham office to complete a generational change with two retirements and at the same time appoint three new partners in Glasgow and London.

Both its prosecution and litigation arm enjoy a good reputation for their work in the pharma and medical technology sector. This not only applies to the lawyers’ work on infringement and nullity suits, but also the patent attorneys’ work in EPO proceedings. Marks & Clerk is firmly established in litigation for manufacturers of traditional pharmaceuticals, underlining this with its ongoing work for Wyeth against MSD. The firm, is however, involved for biotech company Genentech in numerous proceedings concerning antibody drugs.

The patent attorney practice has also a strong focus on electronics and automotive patents and advises clients such as Amazon, Google, Samsung and Toshiba. The litigation team around Graham Burnett-Hall was recently very active in cases involving electronic control units. But despite the team representing Wiko in a dispute with Philips over mobile applications involving FRAND, Marks & Clerk’s litigation team still does not have the same presence here as firms like EIP, Gowling or Simmons & Simmons. When it comes to pharma cases, however, the firm is now almost on a par with its fiercest competitor Carpmaels & Ransford.

Unlike other well-known patent attorney practices, such as Carpmaels, D Young or Kilburn & Strode, which pursue a one- or two-office strategy, Marks & Clerk stands out for its broad presence in the UK with eight offices. As a result, in prosecution work for innovative UK SMEs, Marks & Clerk is clearly ahead of most of its competitors. But its fee earners are less visible in the market than those of other outfits. Unusually, the patent attorneys and lawyers operate in two different companies under the Marks & Clerk brand. This fact is repeatedly commented upon by competitors, who see the firm as less integrated and thus less effective in big litigation cases. Marks & Clerk, however, is holding firmly to this approach and sees no disadvantage in terms of the degree of integration of the two professions. The integrated cooperation between the patent attorneys and lawyers in numerous high-profile pharma cases underlines this.


Pharma cases mainly for originator drug manufacturers, prosecution in broad technical fields.

European strategy

Unlike many of its UK competitors, such as Carpmaels or Mathys & Squire, Marks & Clerk has decided not to open an office in Munich, home to the EPO, so as to avoid disrupting its bilateral relations with German IP firms. It is present on the continent with two offices in France and one in Luxembourg. The firm thus already has offices at two central UPC locations and would have a foot in the door of the new court if it launches. But after Brexit and UK’s departure from the UPC project the urgent question arises as to whether the firm will take on local litigators on the continent. In this case, an office with local litigators in Germany, especially in Munich, would complete the offering. Marks & Clerk’s mixed approach, tried and tested over many years, would provide a good basis for litigation work at the UPC. But regardless of the UPC start, it has taken steps to become a global IP firm much earlier than its main European rivals, with two offices in China and Canada, and one each in Malaysia and Singapore.
