For nearly three decades, our clients’ satisfaction has remained the best proof of the quality of our work. The entire P&TS team is also proud to be regularly distinguished by its peers: this year again, our recognised intellectual property law firm features in the most prestigious independent rankings in the sector.
P&TS recognised by IP STARS
P&TS features once again in IP STARS, the leading specialist guide for companies or individuals looking for experienced legal practitioners to deal with contentious and non-contentious intellectual property issues.

Three of our team members are also listed in this prestigious guide:
- Christophe Saam, Founder and CEO: his profile on IP Stars 2026.

P&TS awarded bronze in the IAM Patent 1000 rankings
This recognition echoes that received a few months ago from IAM, which also produces an authoritative annual ranking in the field. P&TS features in the “Patent 1000” rankings and is awarded bronze this year, with a highly complimentary comment:
“P&TS distinguishes itself with a technically sophisticated and internationally qualified patent team, with attorneys admitted across multiple European jurisdictions. The firm has built a strong reputation in high-tech fields, including software, telecommunications, semiconductors and microtechnology, while also maintaining solid capabilities in life sciences and watchmaking. Its strength lies in the team’s deep technical grounding, with many practitioners trained in engineering and physics, enabling it to handle complex, innovation-driven mandates in areas such as AI, blockchain and fintech.”
