10.6.9 Summary proceedings

District courts “shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.”200 Effective utilization of the summary judgment process is especially important in patent cases because such cases present so many complex issues. Summary judgment can play a critical role in resolving the case or narrowing or simplifying the issues, thereby promoting settlement or simplifying the trial. Conversely, the summary judgment process in a patent case can put a significant burden on the court, particularly if the parties file numerous, voluminous motions.

Effective management of the summary judgment process in patent cases requires an understanding of the types of issues that drive most patent cases, how they typically unfold over the life of a case, and if and when they are amenable for summary adjudication. The timing of summary judgment motions can be critical: if summary judgment proceedings are held too early for a given case, questions of fact that would have been resolved at a later stage preclude summary judgment. However, deferring summary judgment too long risks wasting the time and resources of the parties and the court on issues that limited discovery could have resolved. Distinguishing questions of law from questions of fact

FRCP 56(a) authorizes summary adjudication of issues of law, where there is no disputed question of fact. That is, a court may only entertain summary judgment of pure questions of law, mixed questions of law and fact on which there is no genuine dispute as to any material fact, and undisputed questions of fact. These distinctions are especially subtle in patent litigation, reflecting the complex interplay of fact and law. Furthermore, even though the ultimate claim construction determination is a question of law potentially based on subsidiary questions of fact, the subsidiary facts are within the province of the court, thereby expanding the range of issues that can be resolved on summary judgment. The common issues in most patent litigation – novelty, nonobviousness, and adequacy of written description – involve factual questions or are questions of law based on underlying questions of fact.

The issues least amenable to summary judgment are typically those that have the following characteristics: (1) require a high burden of proof, (2) are questions of fact, (3) are broad issues requiring the movant to establish a wide range of facts, and (4) involve subjects about which the underlying facts are typically disputed. One of the most vexing questions in U.S. patent law today is the extent to which patent eligibility can be resolved at the motion to dismiss or summary judgment stage of litigation.201 Multi-track approach

The information necessary for assessing summary judgment emerges during discovery, case management conferences, claim construction, and other pre-trial processes. It is useful, therefore, to approach summary judgment case management as a multi-track process: (1) claim construction-related, (2) non-claim construction-related, and (3) off-track. Notwithstanding the caution about diverting judicial resources from claim construction, there may be an issue that arises early in the litigation that does not require claim construction and that can either resolve the entirety of the case or substantially streamline the case.

For example, Section 271(a) of the Patent Act imposes infringement liability on persons who “without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent.” Whether an allegedly infringing act occurred within, or outside of, the United States is a question of law, whereas whether an act occurring within the United States is sufficient to constitute a sale, offer to sell, use, manufacture, or importation is a question of fact. Typically, the parties agree that a certain set of events took place in certain locations, but dispute the conclusions to be drawn from these events as they relate to infringement. As a result, both questions – the locus and the characterization of the acts – are often amenable to summary judgment. Such a decision does not implicate claim construction and, therefore, might usefully be addressed early in the litigation process. The summary judgment process and hearing

Notwithstanding the usefulness of summary adjudication in streamlining and resolving some patent cases, the potential exists for parties to inundate the court with summary judgment motions that can disrupt orderly and efficient case management. Consequently, courts have developed a variety of case management techniques for streamlining the summary judgment process, including (1) pre-screening – requiring the parties to file concise letter briefs requesting permission to file summary judgment followed by a telephone hearing to discuss the strengths and weaknesses of the proposed motion(s); (2) quantitative limitations, such as restricting the number of summary judgment motions and the total number of briefing pages, or consolidating motions into a single briefing; and (3) multiple rounds of summary judgment motions. These approaches are not mutually exclusive, and each has advantages and disadvantages based on the nature of the case and contentiousness of the parties. The first approach enables the judge to screen cases more efficiently: competent counsel can usually convey enough information to the court in two to three pages and five minutes of oral argument to enable the court to evaluate whether the substance of a proposed motion justifies a full briefing. The second approach motivates the parties to prioritize their motions. The third approach promotes efficient staging.

Most judges opt for an oral hearing on summary judgment motions. There is rarely any need for live testimony because the court cannot resolve factual disputes through summary adjudication. Live testimony can, however, be useful where declarations submitted by the parties do not squarely address each other and create the perception of a question of material fact when, in reality, one might not exist. The court might want to have a technology tutorial focused on the particular issues presented by the summary judgment motion(s), especially if the claim construction technology tutorial did not cover these areas. The length of time needed for a summary judgment motion varies widely depending on the court’s preferences and the scope and nature of the issues at stake.
