Inventors often wonder whether their invention will meet the Patent Office’s criteria for a patent. Generally, the Patent Office grants patents only to inventions that are novel (new) and non-obvious in light of existing technology at the time of filing. The Patent Office avoids granting patents for inventions that already exist or that are merely obvious variations of known technology.
Novelty vs. Non-Obviousness
Determining novelty is often straightforward, but non-obviousness is more complex. Non-obviousness is based on several factors, including:
- Scope and content of prior art (existing technology).
- Level of skill in the relevant field.
- Differences between the claimed invention and prior art.
- Objective evidence supporting non-obviousness.
Opinions on what constitutes an “obvious” invention vary widely, depending on the perspective and expertise of the evaluator. For instance, an expert in the field might find an invention obvious due to its simplicity, whereas someone less experienced might see it as complex and thus non-obvious.
Supreme Court Ruling in KSR International Co. v. Teleflex Inc.
In KSR Int. Co. v. Teleflex Inc., 550 U.S. 398 (2007), the U.S. Supreme Court reshaped the obviousness standard. The Court criticized the rigid approach previously used and called for a more flexible obviousness test. The ruling rejected the idea that a combination is non-obvious simply because it was “obvious to try.”
Instead, the Court emphasized that:
- If there is a design need or market pressure and a finite number of predictable solutions, a person of ordinary skill would naturally pursue those solutions.
- If these efforts lead to expected success, the result is likely due to ordinary skill and common sense rather than true innovation.
In these cases, the fact that a combination was obvious to try could show it was obvious under 35 U.S.C. § 103.
Federal Circuit’s Commentary in In re Kubin
The Federal Circuit reinforced these principles in In re Kubin, 561 F.3d 1351 (Fed. Cir. 2009), clarifying that:
- An invention is obvious if a skilled person would pursue known options from a finite number of predictable solutions.
- An invention is non-obvious if it represents more than a predictable use of prior art elements according to their established functions.
The KSR decision was extended to all fields of invention, including unpredictable fields like biotechnology. The ruling underscores that the obviousness standard applies universally, without categorical exceptions for certain types of inventions.
Key Takeaway
The Supreme Court’s flexible approach in KSR and subsequent cases like In re Kubin provide clear guidance: predictability and finite solutions can indicate obviousness, even in complex fields. Inventors should focus on showing how their inventions exceed predictable uses of prior technology to establish non-obviousness.
