Declaratory Judgment

A declaratory judgment (DJ) action is a federal lawsuit brought by a party that fears being sued for patent infringement, seeking an affirmative judgment that the patent is not infringed or is invalid: LEGAL BASIS: the Declaratory Judgment Act, 28 U.S.C. § 2201, authorizes federal courts to declare the rights and legal relations of parties in cases of 'actual controversy'; WHAT A DJ ACTION SEEKS: (1) NON-INFRINGEMENT: a judgment that the plaintiff's product or process does not infringe the defendant's patent; (2) INVALIDITY: a judgment that the patent is invalid under 35 U.S.C. § 102, § 103, or § 112; (3) UNENFORCEABILITY: a judgment that the patent is unenforceable (e.g., due to inequitable conduct or prosecution laches); (4) COMBINATION: DJ plaintiffs often seek all three; EFFECT: a favorable DJ judgment eliminates the threat of infringement damages and prevents the patent owner from obtaining an injunction against the DJ plaintiff; WHY FILE A DJ ACTION: (1) CONTROL TIMING: the DJ plaintiff chooses when litigation begins, not the patent owner; (2) CONTROL FORUM: the DJ plaintiff can often select a favorable venue (e.g., near home operations); (3) RESOLVE UNCERTAINTY: companies in licensing negotiations or under threatening letters can resolve patent risk without waiting indefinitely; (4) PREVENT PATENT OWNER FROM FORUM SHOPPING: once a DJ is filed, the patent owner's ability to file in a preferred forum is affected by first-to-file rules.

The Declaratory Judgment Act requires an 'actual controversy' — and MedImmune v. Genentech fundamentally changed how courts assess this requirement in patent cases: PRE-MEDIMMUNE STANDARD (FEDERAL CIRCUIT): before 2007, the Federal Circuit required a 'reasonable apprehension of imminent suit' — a two-part test: (1) the plaintiff must have a reasonable apprehension that the patentee will sue; AND (2) the plaintiff must have engaged in conduct constituting infringement or have made meaningful preparations to engage in such conduct; MEDIMMUNE, INC. v. GENENTECH, INC. (S.Ct. 2007): the Supreme Court rejected the 'reasonable apprehension of suit' test as too narrow; held that the Constitutional standard ('actual controversy') is satisfied if a real dispute exists between parties with adverse legal interests — not necessarily an imminent lawsuit threat; CURRENT STANDARD: an actual controversy exists when: (1) there is a definite and concrete dispute between parties; (2) the parties' legal interests are adverse; (3) there is sufficient immediacy and reality that a declaratory judgment would have practical effect; WHAT CREATES AN ACTUAL CONTROVERSY: (a) patent owner sent a cease-and-desist letter or demand letter; (b) patent owner has sued the DJ plaintiff's customers for related products; (c) patent owner has communicated a belief that the DJ plaintiff's product infringes (even in licensing negotiations); (d) patent owner has sued others in the industry for the same technology; (e) licensee believes it is paying royalties on an invalid patent (MedImmune); WHAT MAY NOT CREATE A CONTROVERSY: a patent owner's mere ownership of a patent — without more — does not create DJ standing; patent owners sometimes 'clear the air' with a covenant not to sue to defeat DJ jurisdiction.

Venue for DJ actions in patent cases is governed by general federal venue statutes — not the patent-specific § 1400(b) venue rule: DJ VENUE STATUTE: 28 U.S.C. § 1391 governs venue for DJ actions (not § 1400(b), which applies to patent infringement suits); under § 1391: venue is proper in any district where any defendant resides (if a corporation, where it is incorporated or has principal place of business) OR where a substantial part of the events giving rise to the claim occurred; IMPORTANT DISTINCTION: the patent venue reform of TC Heartland v. Kraft Foods (S.Ct. 2017) restricted where patent OWNERS can file infringement suits to § 1400(b); but this restriction does NOT apply to DJ plaintiffs — they can file in broader venues under § 1391; STRATEGIC VENUE SELECTION: because the DJ plaintiff controls when and where to file first, they can choose: (1) a forum near their own operations (favorable to DJ plaintiff's witnesses and experts); (2) a forum known for efficient patent litigation; (3) a forum in the Federal Circuit or district known for favorable law on the specific validity issue; FIRST-TO-FILE RULE: once a DJ suit is filed, the patent owner's ability to select a different forum for an infringement suit is constrained by the first-to-file rule; courts in the patentee's preferred forum may defer to the earlier-filed DJ action; PATENT OWNER RESPONSE: patent owners can file an infringement suit in their preferred forum immediately after (or anticipating) a DJ filing; courts sometimes dismiss or transfer DJ actions filed in anticipation of infringement suits; CONVENIENCE AND EFFICIENCY: courts have discretion to dismiss or transfer DJ actions to a more convenient forum under 28 U.S.C. § 1404(a).

A DJ action is a powerful offensive tool but carries significant strategic tradeoffs: ADVANTAGES OF FILING A DJ: (1) FORUM SELECTION: as the plaintiff, the DJ filer chooses the venue, which can be strategically important (near home operations, favorable local rules, efficient docket); (2) TIMING CONTROL: the DJ filer decides when litigation commences — may be before the patent owner is ready; (3) RESOLVE LICENSING UNCERTAINTY: companies in extended licensing negotiations can use a DJ threat to pressure settlement or use it to exit bad-faith negotiations; (4) PREVENT MULTI-FRONT ATTACKS: if the DJ filer is the first to file, it may consolidate all claims in one forum rather than facing suits in multiple favorable forums chosen by the patentee; (5) INVALIDITY CHALLENGE WITHOUT WAITING: particularly useful when IPR (PTAB) is unavailable (past the 1-year filing bar) — DJ actions have no time limit; DISADVANTAGES OF FILING A DJ: (1) WAIVING SURPRISE: filing tells the patent owner that the DJ plaintiff is manufacturing or planning to manufacture the accused product; the patent owner learns about the threat before they would have detected it independently; (2) STARTING THE CLOCK: once litigation starts, discovery, legal fees, and management burden begin immediately; (3) ESCALATING CONFLICT: a DJ filing may eliminate any remaining settlement possibility and force full litigation; (4) RISK OF INFRINGEMENT FINDING: a favorable ruling is not guaranteed — an adverse ruling means both infringement AND invalidity are resolved against the DJ plaintiff; (5) JURISDICTIONAL UNCERTAINTY: if the patent owner contests the DJ's actual controversy, the court may dismiss for lack of jurisdiction; COVENANT NOT TO SUE: patent owners can sometimes defeat DJ jurisdiction by offering a binding covenant not to sue the DJ plaintiff on the specific products at issue.

Patent owners have several mechanisms to defeat or narrow DJ jurisdiction: COVENANT NOT TO SUE: if the patent owner provides a binding, unconditional covenant not to sue the DJ plaintiff for infringement of the specific patent with respect to the specific products at issue, courts will typically dismiss the DJ action for lack of actual controversy; the covenant must be broad enough to eliminate all reasonable apprehension; partial covenants (covering only some products or some claims) may not be sufficient; CARDINAL CHEMICAL CAVEAT: even if a DJ action is dismissed, invalidity counterclaims in related infringement suits may proceed separately; LIMITING SCOPE: patent owners can sometimes argue that the DJ plaintiff lacks standing as to certain claims or patents, narrowing the scope of the DJ action; MOTION TO DISMISS: the patent owner can move to dismiss under Fed. R. Civ. P. 12(b)(1) for lack of subject matter jurisdiction if there was no actual controversy at the time of filing; TRANSFER MOTION: patent owners can seek to transfer the DJ action to their preferred venue under § 1404(a), arguing inconvenience or prior pending case considerations; COUNTERCLAIM FOR INFRINGEMENT: patent owners can file a counterclaim for infringement in the DJ action, which ensures the infringement question is litigated even if the DJ court might otherwise dismiss; EXCEPTIONAL CASES: if a DJ filing is found to be improper (e.g., filed for harassment with no real infringement concern), attorney fees may be available to the patent owner under § 285.
