Hardware or Software? How Austin Innovators Are Misclassifying Their Patents (And Losing Value)

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

If you spend enough time looking at patent filings from Austin’s emerging tech sector, you start to notice a recurring and expensive mistake: founders are trying to force complex, hybrid innovations into traditional "software" or "hardware" boxes.

When I was on the fabrication floor working with laser lithography, the line between the physical machine and the computational models controlling it was absolute. You had the hardware guys, and you had the software guys. Today, in fields like robotics, IoT edge computing, and autonomous systems, that line has completely dissolved. The innovation is the interplay.

Yet, when companies file for patents, they often default to claiming only the code (which faces brutal Alice Section 101 eligibility challenges) or only the physical device (which often misses the actual inventive leap).

Here is why misclassifying your hybrid innovation limits your competitive protection, and how to draft claims that actually protect the commercial value of what you’ve built.

The Problem with "Pure Software" Claims in Hybrid Systems

When you isolate the computational aspect of a hybrid system and claim it purely as a software method, you invite immediate scrutiny under 35 U.S.C. § 101. The USPTO examiner will look at the claim and ask: "Is this just an abstract idea running on generic computer hardware?"

If your claims just say "receiving data, processing data with an algorithm, and outputting a result," you will likely face a rejection. You are essentially asking the patent office to protect math.

The Hardware Trap: Missing the Intelligence

Conversely, if you focus solely on the physical structure—the sensors, the actuators, the housing—you might get a patent, but it will be fragile. If your actual competitive advantage is how your proprietary machine learning model optimizes the sensor data to adjust the actuators in real-time, a patent that only claims the physical arrangement of the sensors is nearly useless. A competitor can build the exact same hardware configuration, write their own code, and bypass your patent entirely.

The Solution: Claiming the Technical Improvement

The most defensible claims for hybrid innovations don't ignore the hardware to protect the software, nor do they ignore the software to protect the hardware. They claim the specific technical improvement that the software creates within the hardware system.

Instead of claiming an algorithm in a vacuum, your claims need to describe how the specific algorithmic approach improves the physical functioning of the device.

• Does your software reduce latency in the mechanical response time?

• Does it reduce power consumption in the edge device?

• Does it allow a lower-resolution physical sensor to achieve high-resolution output through computational correction?

  
  

Those are not abstract ideas; those are concrete technical improvements to computer or mechanical functionality.

Drafting for the Overlap

Drafting for this intersection requires an attorney who understands both the physics of the hardware and the architecture of the code. If your counsel only understands software, they will miss the mechanical constraints. If they only understand hardware, they won't know how to articulate the algorithmic leap.

If your Austin-based company is building technology where the software and the physical world collide, your IP strategy needs to reflect that reality. Don't let your core innovation fall through the cracks between the hardware and software patent classifications.
