Between 1976 and 2025, the United States Patent and Trademark Office granted 9.36M patents. This half-century of innovation encompasses everything from the personal computer revolution to the rise of artificial intelligence.

Patent Grants Over Time

The fivefold growth in annual patent grants since 1976 reflects both more invention and the growing strategic importance of intellectual property. The 2008 dip and 2020 COVID disruption are visible in the data.

Patent grants have grown dramatically, from roughly 70,000 per year in the late 1970s to over 350,000 per year in recent times. Utility patentsutility patentA patent granted for a new and useful process, machine, manufacture, or composition of matter. The most common patent type, representing over 90% of US grants. -- which protect new inventions and processes -- make up over 90% of all grants. Design patents, protecting ornamental designs, have also seen steady growth.

The growth has not been steady. The 2008 financial crisis caused a notable dip, and patent office backlogs have created year-to-year volatility. But the overall trajectory is clear: more people and organizations are seeking patent protection for their inventions than ever before.

Patent Complexity: Claims Per Patent

Average and median number of claims per utility patent. More claims generally indicate more complex inventions.
The widening gap between average and median claims suggests a growing subset of patents with very broad claim sets — a pattern consistent with defensive patenting and patent thicket strategies.

Patents have become significantly more complex over time. The average number of claims per patent has increased steadily, reflecting the growing sophistication of inventions and the strategic importance of broad patent coverage. Each claim defines a specific aspect of the invention that is legally protected.

Time from Filing to Grant

Patent pendency functions as a hidden cost of innovation. The 2000s spike coincided with the computing and telecom boom, when timely patent review mattered most for fast-moving industries.

The time it takes for a patent to go from application to grant has fluctuated considerably. In the early 2000s, growing backlogs pushed average pendency times to over 3 years. The USPTO has made efforts to reduce these times, but the increasing complexity of technology and the sheer volume of applications continue to challenge the system.

Having explored the overall scale and trajectory of US patent activity over five decades, the next chapter examines which technologies have driven this growth. The fivefold expansion in patent output masks dramatic shifts in the composition of innovation -- from chemistry and mechanical engineering toward computing, semiconductors, and digital communication.
