For more than a decade, many U.S. startups and small innovators have faced a growing challenge in protecting their intellectual property. While patents are meant to safeguard inventions and reward risk-taking, loopholes in the Patent Trial and Appeal Board (PTAB) process have made it easier for large corporations — and even foreign competitors — to repeatedly challenge the patents of smaller companies.
New reforms proposed by the U.S. Patent and Trademark Office (USPTO) aim to change that.
The proposal would strengthen the U.S. patent system by limiting duplicative challenges and restoring balance between innovators and those accused of infringement. At its core, the reform addresses a strategy widely known as “efficient infringement.” In this model, large companies knowingly use patented technologies and then challenge those patents repeatedly, betting that smaller inventors lack the time or resources to defend them through endless legal proceedings.
This practice has had real consequences across industries — from semiconductors and medical devices to cybersecurity and wireless technology. Startups and smaller companies often face dozens of patent challenges on the same core inventions, creating costly delays and uncertainty even when courts have already upheld the patents.
The USPTO’s proposed rule changes introduce several common-sense guardrails. Petitioners challenging a patent would need to commit to one forum rather than pursuing parallel attacks across multiple venues. PTAB would also decline to re-litigate patents that have already been upheld in court or in prior decisions, and it would avoid duplicative reviews when another tribunal is likely to reach a decision first.
These changes could make a meaningful difference for America’s innovation ecosystem. Small businesses and startups generate a disproportionate share of breakthrough technologies — often accounting for nearly half of the most disruptive innovations that reshape markets. Ensuring they can defend their intellectual property is critical to sustaining venture investment and maintaining leadership in fields like AI, semiconductors, life sciences, and cybersecurity.
The reforms may also reduce attempts by foreign entities to use the U.S. patent system to challenge American innovators, an issue policymakers have increasingly highlighted in national security discussions.
Ultimately, a predictable and fair patent system is essential for economic growth. By restoring integrity and efficiency to the PTAB process, the proposed reforms would help ensure that inventors, entrepreneurs, and investors can rely on the patent rights that power American innovation.
