Understanding Patent Law for Tech Startups: General Information from an Austin Engineer-Turned Patent Attorney

By Sean Christian Connolly, USPTO Registered Patent Attorney, B.S. Physics, Former Semiconductor Engineer — Austin, Texas

I’ve worked with a lot of tech startup founders over my 17 years of patent practice, and I’ve noticed something consistent: most of them come to me with a general sense that patents are important but a lot of uncertainty about what patents actually do, when to file, and whether their specific technology is even patentable.

That uncertainty is completely understandable. Patent law has its own language, its own timelines, and its own logic — and most founders are focused on building their product, not navigating the USPTO. But getting the IP fundamentals right early can make a significant difference in your company’s long-term competitive position and valuation.

Before I was a patent attorney, I spent over seven years as an engineer in the semiconductor industry. That background shapes how I work with tech startup clients — I don’t just understand the legal side, I understand the technology. When a founder describes their machine learning architecture or their chip design to me, I’m not nodding politely and hoping I catch enough to write a decent application. I understand what they built.

Here’s what I want every Austin tech startup founder to know about patent law.

Patents Are About Exclusion, Not Permission

This is the most fundamental thing to understand and the most commonly misunderstood. A patent doesn’t give you the right to do anything. It gives you the right to exclude others from making, using, selling, or importing your invention for up to 20 years.

You can practice your invention freely without a patent if no one else has patented it; however, you have no recourse to stop someone from using it. The value of a patent is purely exclusionary — it’s a legal mechanism to stop competitors from copying what you built.

For a tech startup this matters because your patent strategy should focus on protecting what gives you your competitive advantage — the specific innovations that competitors would most want to copy and that would be hardest for them to develop independently.

What’s Actually Patentable in Tech?

Software, AI systems, semiconductor innovations, and hardware inventions can all be patented — but the claim strategy matters enormously. The Supreme Court’s Alice decision created heightened scrutiny for software and AI patents, and applications that describe inventions in abstract functional terms consistently fail.

What succeeds are applications that describe the specific technical implementation — how the invention works at an architectural level, what concrete technical problem it solves, and what specific technical improvement it makes over existing approaches. In my experience, founders who can explain their technology in genuine engineering detail have a significant advantage in patent prosecution, because that technical depth translates directly into better claims.

My semiconductor engineering background means I can have that engineering-level conversation with founders building technically sophisticated products. That conversation is where the best patent applications start.

When to File — Earlier Than You Think

The most common timing mistake I see from startup founders is waiting too long to file. The US patent system is first-to-file, which means priority goes to whoever files first — not whoever invented first. If a competitor independently develops the same innovation and files before you, they get the patent.

More importantly: any public disclosure of your invention can affect your patent rights. A conference presentation, a published paper, a product launch, a detailed investor pitch without an NDA — all of these start clocks running. In most foreign countries there is zero grace period, meaning a single public disclosure before filing permanently bars you from obtaining international patent protection.

My consistent advice: file a provisional patent application before you disclose publicly. A well-drafted provisional establishes your filing date immediately at a lower cost than a full application, gives you 12 months of patent pending status, and preserves your international filing rights. It buys you time to refine the invention and assess market viability before committing to the full prosecution costs.

Patents as a Business Asset

Austin’s venture capital community pays attention to IP. A pending patent application — especially one covering a genuinely novel core technology — signals to investors that your innovation is real, that you’ve thought seriously about protecting your competitive advantage, and that the company has defensible assets.

I’ve had startup clients tell me that having a patent pending materially helped their seed round conversations. It’s not always decisive, but it’s rarely irrelevant.

Beyond fundraising, patents give you leverage. They give you the ability to license your technology, to assert your rights against infringers, and to build a portfolio that grows in value as your company grows. A startup that builds its patent portfolio strategically from the beginning is in a fundamentally different position than one that tries to retrofit IP protection after the fact.

One Practical Note

If you’re an Austin tech startup founder reading this and wondering whether your specific technology is patentable, the honest answer is: it depends on the details.
