大学発ベンチャーと民間企業間の特許ライセンス契約を巡る訴訟事例

大学発のベンチャー企業と民間企業の間で起きた、特許ライセンス契約を巡る訴訟事例では、争点が、実施料の支払い条件である共同研究契約などが締結されなかったことに対し、企業側に信義則違反の妨害があったか否かという点でした。
裁判所は、大学側の不十分な情報開示や関連特許の隠匿を重く見て、企業側の契約見送りを正当な判断と認定し、大学側の請求を棄却しました。
この事例は、産学連携における技術認識の乖離や知財管理の甘さが招く法的リスクを浮き彫りにしています。
この大学発ベンチャーと民間企業間の特許ライセンス契約を巡る訴訟事例からの教訓について、生成AIに深掘りさせました。さらに、結果をNotebookLMでインフォグラフィック、スライド資料にさせました。

A Litigation Case Concerning a Patent License Agreement Between a University Spin-Off Venture and a Private Company
In a litigation case arising from a patent license agreement between a university-originated venture company and a private company, the central issue was whether the private company had wrongfully interfered, in violation of the principle of good faith, with the fulfillment of conditions for the payment of royalties—specifically, the failure to conclude related agreements such as a joint research contract.
The court placed significant weight on the university side’s inadequate disclosure of information and the concealment of related patents. It determined that the private company’s decision not to proceed with the contract was justified and therefore dismissed the claims brought by the university side.
This case highlights the legal risks that can arise in industry–academia collaboration from gaps in technical understanding and lax intellectual property management.
I asked generative AI to conduct an in-depth analysis of the lessons learned from this litigation concerning a patent license agreement between a university spin-off venture and a private company. The results were further developed into infographics and slide materials using NotebookLM.
