Denver has become one of Colorado’s most active hubs for innovation, attracting entrepreneurs and inventors across industries from biotech to software. But even the most promising inventions can stall when a patent application is filed with hidden errors that aren’t obvious until the USPTO examiner flags them.
These are the mistakes that don’t make headlines—but derail applications all the same.
Misidentifying the Inventors on Your Application
Inventorship is a legal determination, not an organizational one. The named inventors on a patent application must be exactly those individuals who contributed to the conception of the claimed invention—no more, no less.
Why inventorship errors are serious:
Incorrect inventorship can render a patent unenforceable
Adding someone who didn’t contribute—or leaving out someone who did—are both violations
Corrections are possible but require formal proceedings that delay prosecution
This issue arises frequently in collaborative environments like university research labs and Denver-area co-working innovation spaces, where team contributions blur.
Writing Claims That Are Too Narrow From the Start
While vague claims create one set of problems, overly narrow claims create another. A claim that’s too specific may be easily designed around by competitors, leaving your invention with limited real-world protection.
Signs your claims may be too narrow:
Claims that describe only one embodiment of the invention
Specific dimensions or materials included where they aren’t essential to the invention’s function
Dependent claims that add no meaningful scope beyond the independent claim
A strong patent application typically includes a range of claim types—broad independent claims, supported by progressively narrower dependent claims—creating layered protection.
The Problem With DIY Patent Drafting
Filing without professional assistance is legal, but the statistics tell a revealing story. Studies suggest that pro se applicants (those who file without an attorney) receive patents at significantly lower rates than professionally represented filers. In a city like Denver, where competition for intellectual property protection is high, this gap matters.
What professional representation typically adds:
Accurate classification of the invention type (utility, design, plant)
Strategic claim drafting aligned with the inventor’s commercial goals
Knowledge of USPTO examination trends in specific technology areas
That said, many Colorado inventors use a hybrid approach—filing a provisional application independently to establish a priority date, then engaging an attorney to draft the full non-provisional application.
About Patent Drafting Errors
What is the difference between a provisional and non-provisional patent application?
A provisional application establishes a priority date but never becomes a patent on its own. It gives inventors 12 months to file a non-provisional application. A non-provisional application is the complete filing that the USPTO formally examines for grant.
Can I fix errors in my patent application after filing?
Some errors can be corrected through amendment during prosecution. However, new matter—information not present in the original application—cannot be added after the filing date. This makes getting the specification right from the start critically important.
What does “conception” mean in patent inventorship?
Conception refers to forming a definite and permanent idea of the complete and operative invention. Only those who contribute to this mental act qualify as true inventors under U.S. patent law.
How are patent application fees structured at the USPTO?
The USPTO uses a tiered fee structure based on entity size. Large entities pay the full fee, small entities (fewer than 500 employees) pay 40% of that, and micro-entities (qualifying on income and filing history) pay 20%. Checking your entity status before filing in Colorado or anywhere else can save significant money.
What happens if two inventors file for the same invention?
The U.S. now operates on a “first inventor to file” system, established by the America Invents Act of 2013. The patent generally goes to whoever files first, making timely filing a strategic priority.
Precision Builds Patentable Inventions
The margin for error in patent prosecution is thin. Every section of the application—from the abstract to the final claim—serves a legal function. Inventors in Denver and throughout Colorado who invest time in getting the details right, or who partner with qualified professionals, consistently achieve better outcomes. Precision isn’t optional in patent law. It’s the foundation.
