Case Study: How Two Co-Inventors Settled a Dispute Without Litigation

Two engineers — one in Doha, one in Munich — co-invented a modular solar panel mounting system during a joint R&D project. They filed a patent together but never signed a co-inventor agreement. When one wanted to license exclusively to a German manufacturer and the other wanted to license non-exclusively to multiple companies across the GCC, the partnership fractured.

This case study is a realistic composite. Names and specific details have been changed.

The Dispute

Omar (Doha) and Klaus (Munich) were listed as joint inventors on a PCT application covering the mounting system. Without a co-inventor agreement, they had equal, undivided ownership — and under US law (where they had entered national phase), each owner could independently license without the other's consent or any obligation to share revenue.

Klaus signed a term sheet with a German manufacturer for an exclusive licence covering Europe. Omar discovered this when the manufacturer's attorney contacted him for signature confirmation. Omar refused — he wanted non-exclusive licences to multiple GCC manufacturers, which the exclusive European licence would not prevent, but the relationship was now adversarial.

The Resolution

Rather than litigate — which would have cost each party $100,000+ and taken 2–3 years — they engaged a WIPO mediator. Over three sessions spanning six weeks, they reached an agreement:

• Omar would manage licensing in the GCC, Africa, and Asia
• Klaus would manage licensing in Europe and the Americas
• Revenue from each territory would be split 60/40 in favour of the managing partner (compensating for the work of finding and managing licensees)
• Neither could grant an exclusive licence without the other's written consent
• A formal co-inventor agreement was drafted and executed, replacing the informal arrangement

Total mediation cost: $8,000 — split equally. The dispute was resolved in six weeks instead of two years.

The Lesson

Sign a co-inventor agreement before filing. The agreement should specify ownership percentages, who manages licensing in which territories, how revenue is shared, what happens if one party wants to sell, and how disputes are resolved. The iInvent Co-Inventor Agreement template covers all of these provisions. The cost of drafting the agreement upfront: $2,000–$5,000. The cost of not having one: the relationship, the licensing revenue, and potentially the patent itself.
