Key matters:

  • Global patent portfolio development for AI-powered drug discovery company

Jones Day is representing MindRank AI, an artificial intelligence (AI)-powered drug discovery company, in the development of global patent portfolios related to clinical-stage small molecule therapeutics and methods for the treatment of various metabolic disorders.

  • Advisory work and portfolio development for AbbVie

Jones Day provides strategic IP counselling to AbbVie regarding its Clostridium botulinum neurotoxin portfolio, including BOTOX. The team also represents AbbVie in the development and prosecution of global patent portfolios related to SKYRIZI, an interleukin-23 (IL-23) inhibitor for treating inflammatory conditions.

  • Motorola Solutions v Stellar

Jones Day represented Motorola Solutions in a patent dispute with Stellar, which sued Motorola for alleged patent infringement. Motorola filed inter partes reviews challenging the validity of the patents-in-suit.

The PTB initially instituted review; however this was vacated following a Director Review request from Stellar.

Motorola petitioned the Federal Circuit for a writ of mandamus, seeking to reinstate the PTAB’s original decision. This was denied in November 2025.

  • CODA Development et al v Goodyear Tire & Rubber Company et al

Jones Day successfully represented Goodyear and employees in litigation where they were accused of misappropriating trade secrets relating to self-inflating tire technology and incorporating the technology into several US patents.

A victory for Goodyear on all the claims was affirmed by the Federal Circuit in December 2025.

  • Federal Circuit win for Medtronic

The team overturned a $125 million patent infringement judgment at the Federal Circuit for Medtronic involving its replacement heart valve and method of implantation. The Federal Circuit ordered judgment of non-infringement for Medtronic in July 2025.

Jones Day successfully argued that Colibri Heart Valve’s assertion of infringement under patent law's doctrine of equivalents was barred by Colibri's arguments and amendments during the prosecution of its patent application.
