Summary:
For more than a decade, some Members of Congress have considered bills that have proposed
reforms to the law of patent remedies. Under current law, courts may award damages to
compensate patent proprietors for an act of infringement. Damages consist of the patent owner’s
lost profits due to the infringement, if they can be proven. Otherwise the adjudicated infringer
must pay a reasonable royalty. Courts may also award enhanced damages of up to three times the
actual damages in exceptional cases. In addition, courts may issue an injunction that prevents the
adjudicated infringer from employing the patented invention until the date the patent expires.
Finally, although usually each litigant pays its own attorney fees in patent infringement cases, win
or lose, the courts are authorized to award attorney fees to the prevailing party in exceptional
cases.
Some observers believe that the courts are adequately assessing remedies against adjudicated
patent infringers. Others have expressed concerns that the current damages system systematically
overcompensates patent proprietors. Some suggest that the usual rule regarding attorney fees—
under which each side most often pays its own fees—may encourage aggressive enforcement
tactics by “patent assertion entities,” which are sometimes pejoratively called patent trolls.
Damages often occur in the context of a patent that covers a single feature of a multi-component
product. In addition, many of these other components are subject to additional patents with a
fragmented ownership. The courts have developed such principles as the “entire market value
rule” and have also addressed the concept of “royalty stacking,” in order to address these issues.
Legislation was introduced before Congress relating to these matters, but these bills were not
enacted.
Current law allows courts to award enhanced damages in exceptional cases, which ordinarily
applies to circumstances of willful infringement or litigation misconduct. Recent Supreme Court
decisions appear to have increased the likelihood that enhanced damages will be awarded, in
contrast to earlier legislative proposals that were more restrictive.
Bills in the 114th Congress would have called for the prevailing party to be awarded its attorney
fees in patent litigation. Under these proposals, fees would not be awarded if the nonprevailing
party’s position and conduct were justified or special circumstances made the award unjust. This
legislation was not enacted, but it may be reintroduced in the 115th Congress.
Design patents are subject to a special damages statute which asserts that anyone who sells an
“article of manufacture” containing the patented design may be liable to the patent owner “to the
extent of his total profit.” In its 2016 decision in Samsung v. Apple, the Supreme Court ruled that
an “article of manufacture” need not consist of the entire product sold to consumers, but could
also mean a portion of a multi-component product. This ruling appears to have decreased the
damages available for the infringement of design patents that apply to products with multiple
features.
In the 115th Congress, the STRONGER Patents Act of 2017, S. 1390, would modify the principles
governing the award of an injunction against an adjudicated patent infringer. S. 1390 would
establish a presumption that future infringements would cause irreparable injury and that legal
remedies, such as damages, are inadequate to compensate for those infringements. This proposal
would increase the likelihood that patentees could obtain an injunction against infringers.
