Narrative Opinion Summary
In a patent infringement case between Abbott Laboratories and Ortho Diagnostic Systems, Diamedix Corporation sought to intervene after Abbott initiated the suit without including Diamedix, the patent owner. The patents in question involved immunoassay systems for hepatitis detection. Under their exclusive license agreement, Abbott was granted the primary right to sue for infringement, with Diamedix retaining certain rights and the ability to sue if Abbott failed to act. Abbott's suit against Ortho, which included claims of patent invalidity and delay defenses by Ortho, did not acknowledge Diamedix's interests, prompting Diamedix to file a motion to intervene. The district court denied this motion, arguing that Abbott adequately represented Diamedix's interests. However, on appeal, the Federal Circuit reversed this decision, emphasizing that under the Patent Act, the legal titleholder, in this case, Diamedix, must be a party to the infringement action. The court highlighted that Abbott, as a licensee, could not independently pursue the infringement claims without Diamedix, who retained significant rights under the patents. The ruling underscored the necessity of Diamedix's involvement in ensuring proper standing and jurisdiction under Rule 19, preventing potential prejudice to its interests or exposing Ortho to multiple liabilities. The case was remanded for further proceedings, with the district court tasked with addressing the implications of the control clause in the license agreement during subsequent litigation stages.
Legal Issues Addressed
Exclusive Licensee Rights and Obligationssubscribe to see similar legal issues
Application: The court found that Abbott, as an exclusive licensee, did not have sufficient rights to sue independently for infringement without joining Diamedix, the patent owner, due to retained rights by Diamedix.
Reasoning: Abbott contends that it does not need to join Diamedix in the current legal action because an agreement between them transferred all substantial patent rights to Abbott. However, the court disagrees, noting that Diamedix retains significant interests in the '878 and '285 patents.
Intervention as of Right under Federal Rule of Civil Procedure 24(a)(2)subscribe to see similar legal issues
Application: The court reversed the district court’s denial of Diamedix’s motion to intervene, recognizing that Diamedix, as the legal owner of the patents in question, had a significant interest in the litigation that was not adequately represented by Abbott.
Reasoning: Diamedix asserted its right to intervene under Federal Rule of Civil Procedure (Fed. R.Civ. P.) 24(a)(2) due to its legal ownership of the patents, and alternatively under Rule 24(b).

Application: The court held that Diamedix, despite granting an exclusive license to Abbott, still retained sufficient rights in the patents to necessitate its participation in the infringement suit.
Reasoning: Abbott's exclusive license is subordinate to prior licenses held by Diamedix, and although Abbott has a right of first refusal to sue alleged infringers, it cannot ignore infringements without consequences.
Patent Ownership and Right to Sue under the Patent Act of 1952subscribe to see similar legal issues
Application: The court emphasized that under the Patent Act, a patent infringement suit must be brought by the patentee or patent owner, and a licensee cannot independently bring such a suit without the owner.
Reasoning: The court noted that under the Patent Act of 1952, a civil action for infringement must be brought by a 'patentee,' defined to include the legal titleholder of the patent, indicating that parties without title could only sue if they joined the patent owners.
Role of Control Clauses in License Agreementssubscribe to see similar legal issues
Application: The court acknowledged that while Abbott had negotiated control over the prosecution of the suit, the extent of Diamedix's engagement would be determined by the district court in accordance with their agreement.
Reasoning: Diamedix is allowed to participate as a party in the case, but its level of involvement is subject to the terms of its agreement with Abbott, which grants Abbott control over the prosecution of the suit.
