*1017 ORDER
The court, on its own motion, determines as follows:
This сase comes to us on appeal from the decisions of the United States District Court for the Central District of California, following a jury trial, on the infringement, validity, and enforceability of U.S. Patent No. 4,886,491 (the “'491 patent”). Mentor H/S, Inc. v. Med. Device Alliance, Inc., No. CV 97-2431-WDK (C.D. Cal. June 10, 1999) (granting certain of defendants’ motions for JMOL); Mentor H/S, Inc. v. Med. Device Alliance, Inc., No. CV 97-2431-WDK (C.D.Cal. Nov. 19, 1999) (conditionally granting certain of defendants’ motions for a nеw trial). In an order issued December 20, 2000, we invited the parties to submit supplemental briefs on the issue of whether Mentor H/S, Inc. (“Mentor”) had standing to bring suit without joining Sonique Surgical Systems, Inc. (“Sonique”), the apparent legal owner of the patent. Mentor H/S, Inc. v. Med. Device Alliance, Inc., Nos. 99-1532, 00-1165 (Fed.Cir. Dec. 20, 2000). Prior to our order, neither Mentor nor defendants-ap-pellees, Medical Devicе Alliance, Inc., Ly-sonix, Inc., and Misonix, Inc. (collectively, “Medical Device”), had raised the standing issue, either before us or in the district court. The court, having considered thе submissions of the parties, determines that Mentor did not have standing to bring the patent infringement suit without joining the patent owner.
Only a “patentee” can bring an action for рatent infringement. 35 U.S.C. § 281 (1994);
Textile Prods., Inc. v. Mead Corp.,
To determine whether аn agreement constitutes just an exclusive license or instead also transfers “all substantial rights” in a patent, we must ascertain the intention of the parties and examinе the substance of what was granted by the agreement.
Vaupel,
Sonique has retained significant ownership rights in the '491 patent. Sonique can develop and manufacturе products (for sale only to Mentor) and supervise and control Mentor’s product development. Sonique also is obliged to pay the maintenance fees for the patent. Finally, and most importantly, Sonique has the first obligation to sue parties for infringement; failure to take appropriate action against infringers wоuld constitute a breach of the agreement. Mentor only can sue for infringement in the event Sonique fails to do so. In
Vaupel,
the grant of the right to sue for infringement, subject only to thе obligation to inform the patentee, was particularly dispositive of our conclusion that Vaupel was an exclusive licensee with all substantial rights in the patent and could bring suit in its own name.
Vaupel,
Mentor argues that it satisfies the constitutional requirements for standing, and that defendants have waived any other issues regarding its standing by failing to raise them in the district court. Mentor argues further that because the non-constitutional issues regarding its standing are “prudential” in nature, we lack jurisdiction to consider them for the first time on appeal. While we agree that Mentor, as an exclusive licensee, satisfies the constitutional requirements for standing,
see Prima Tek II v. A-Roo Co.,
Standing to bring a patent infringement suit is circumscribed by 35 U.S.C. § 281, which provides that “[a] patentee shall have remеdy by civil action for infringement of his patent.” 35 U.S.C. § 281;
Abbott Labs. v. Diamedix Corp.,
47
F.3d 1128,
1130, 33 USPQ2d 1771, 1773 (Fed.Cir.1995). Thus, the rule that an exclusive licensee who does not have all substantial rights in a patent must join the patent owner is derivеd from the statute that defines what parties have standing to sue for patent infringement. Under these circumstances, the issue of whether an exclusive licensee has sufficient rights in a patent to bring suit in its own name is jurisdictional and, therefore, is not waived by a party’s failure to raise the issue in the district court.
See Indep. Wireless Tel. Co. v. Radio Corp. of Am.,
In the alternative, Mentor urges us to effect Sonique’s joinder on appeal. Medical Deviсe has not had an opportunity to respond to that argument. Ordinarily, when the plaintiff who brought suit is found to lack standing, the suit is dismissed.
See, e.g., Textile Prods.,
IT IS ORDERED THAT:
(1) Mentor is invited to file a motion pursuant to Rule 21 of the Federal Rules of Civil Procedure to add Sonique as a party plaintiff, and a brief in support thereof of no more than ten pages in length. Mentor’s motion and brief shall be filed within 14 days of this order.
(2) Medical Device is given 15 days from the filing of Mentor’s motion and brief, if any, to file a response thereto of no more than ten pages in length.
(3) If the motion contemplated by paragraph (1) is not filed, Mentor’s appeal will be dismissed.
