Quick Summary
Herbert Markman (plaintiff) sued Westview Instruments, Inc. (defendant) for patent infringement related to an inventory control system. The dispute centered on the interpretation of ‘inventory’ within Markman’s patent claim.
The Supreme Court had to determine whether claim construction was a task for the judge or jury. Ultimately, it concluded that judges are better equipped to interpret legal documents and upheld the lower court’s ruling in favor of Westview, stating that it is a matter of law for judicial resolution.
Facts of the Case
Herbert Markman (plaintiff) held a patent for an inventory control system designed for dry cleaning businesses. Westview Instruments, Inc. (defendant) developed a product that Markman claimed infringed on his patent rights. The central issue revolved around the interpretation of the term ‘inventory’ as used in the patent claim. Markman argued that Westview’s system, which tracked invoices and transaction totals, infringed upon his patent that he contended was aimed at monitoring physical articles of clothing.
The dispute led Markman to initiate a lawsuit for patent infringement. After a jury ruled in favor of Markman, Westview contested the decision, prompting the district court to overturn the jury verdict on the grounds of non-infringement due to its interpretation of the term ‘inventory’.

I.R.A.C. Format
Issue
Whether the interpretation of patent claims, specifically terms of art within those claims, falls under the purview of the court or is subject to a jury determination under the Seventh Amendment.
Rule of Law
The interpretation of a patent claim is an issue for the court to decide as a matter of law. This rule is based on the court’s expertise in interpreting legal documents and its ability to understand technical aspects and terms of art within patents.
Reasoning and Analysis
The Supreme Court unanimously decided that the task of interpreting patent claims is exclusively within the province of the court. The Court reasoned that historically, there was no jury practice in 18th-century England for construing terms in patent documents, and thus, there is no Seventh Amendment right to a jury trial on the question of patent claim construction.
Furthermore, judges are considered better suited to interpret legal documents due to their training and experience. The Court also noted that while expert testimony might be necessary to understand certain technical aspects of a patent, it ultimately falls upon judges to interpret the document’s meaning following such testimony, not upon juries. This approach aligns with promoting consistency and uniformity in patent law interpretation.
Conclusion
The Supreme Court affirmed the decision of the Court of Appeals for the Federal Circuit, holding that claim construction in patent law is a matter for judicial determination and not for a jury.

- The Supreme Court held that patent claim construction is a judicial function, not a jury question.
- This case established that judges have exclusive authority to interpret the scope and meaning of patent claims.

Relevant FAQs of this case
What role does a judge play in interpreting legal documents?
Judges perform a crucial role in legal interpretation, applying principles of statutory and case law, and using discretion to reach informed and equitable decisions.
- For example: In a contract dispute, a judge might interpret ambiguous terms based on the common law principle of contra proferentem, which resolves ambiguities against the party who drafted the document.
Why is consistency important in legal interpretations?
Consistency ensures fairness, predictability, and efficiency within the legal system, allowing individuals and entities to rely on established interpretations when conducting their affairs.
- For example: When multiple courts interpret a regulation in the same way, businesses can devise compliant strategies without fearing contradictory rulings from different jurisdictions.
How does technical expertise contribute to understanding complex legal issues?
Technical expertise allows a more accurate and detailed understanding of specialized areas of law, leading to precise and informed rulings within those fields.
- For example: A judge with expertise in intellectual property law would be better equipped to understand the nuances of patent claim language, much like in Markman v. Westview Instruments, Inc., ensuring more reliable judgments.
