Restricting Patent Scope: The Debate on Limiting Computer Implemented Inventions in Patent Law

In recent years, there has been an increasing debate about the patentability of computer-implemented inventions. The U.S. Supreme Court's Alice decision and proposed legislation such as the Patent Eligibility Restoration Act (PERA) aim to limit the patentability of certain types of inventions. 

While these measures have their supporters who believe they protect against overly broad patents, they also face criticism for potentially stifling innovation. This article will delve into the pros and cons of limiting computer-implemented inventions in patent law.

Challenges in patenting

Computer-implemented inventions in patent law often face opposition in terms of their inventive steps and sufficiency. Thorough technical demonstration is crucial for their eligibility to be patented.

Identifying the technical issue that the invention addresses is key. Complexity arises when non-technical elements are involved or when the solution lacks impact on technical processes.

Prior art

Prior art refers to any material, including previous patents or publications, that demonstrates the public accessibility of a claimed invention before the filing of a patent application.

A comprehensive search should be conducted to identify relevant prior art. This involves searching existing patents, scholarly articles, websites, and other resources. Properly referring to and distinguishing the novel aspects from pre-existing knowledge is vital in addressing objections related to prior art.

Inventive step

Establishing an inventive step for computer-implemented inventions can be challenging. The European Patent Office follows a problem and solution methodology to determine this criterion. This involves identifying an objective technical issue solved by distinct features from the closest prior art document.

When assessing inventiveness, it is important not only to consider computer implementations but also to evaluate if there are any claim elements with technical character. For example, incorporating enhanced model architecture in AI development may pose prosecution challenges.

Sufficiency

Sufficiency is crucial when submitting a patent application. The description should include enough detail for someone with technical knowledge to replicate the invention successfully.

In fields like artificial intelligence (AI) and machine learning, it becomes even more important to clearly specify the training data used. The application should indicate the process of obtaining this data and include criteria for determining what qualifies as "good" training information.

Patentable vs non-patentable

The borderline between patentable and non-patentable subject matter can sometimes appear blurry, especially for computer-implemented inventions and their claimed components. The US Patent and Trademark Office (USPTO) evaluates the patent eligibility of computer-implemented inventions based on abstract ideas. If an invention is purely a mathematical concept or a mental process without a physical component, it may not qualify for patent protection.

Best practices for patenting computer inventions

Inventors can increase their chances of obtaining robust patent protection for their computer-implemented inventions by using the following guidelines:

1. Seek experienced legal counsel: Hire a knowledgeable attorney specialized in protecting computer-implemented inventions through patents.
2. Apply the Mayo/Alice test: The Mayo/Alice test refers to the legal test established in two US Supreme Court rulings, Mayo Collaborative Services v. Prometheus Laboratories (2012) and Alice Corp v. CLS Bank International (2014). This test is used to determine whether an invention or process claims eligible subject matter. Use this test to assess patent eligibility and address any concerns.
3. Gather comprehensive information: Collect all relevant details about the invention before entering negotiations.
4. Provide clear specifications: Include a concise overview of the technology, clear operating instructions, examples, and potential improvements in the filing specifications.

Avoiding common pitfalls

When patenting computer-implemented inventions, it's important to be aware of common risks. These include insufficient disclosure, premature information sharing, and incomplete submissions. To mitigate these risks:

1. Pay attention to wording and legal requirements to ensure clarity in claims and descriptions while meeting novelty and nonobviousness standards.
2. Consider filing provisional patents as a form of insurance against future issues.
3. Establish strong relationships with co-inventors before applying for a patent to avoid potential conflicts.
4. Study European Patent Conventions for additional insights into the patent process.

Computer-implemented inventions have both pros and cons.

While they seek to prevent broad patents and foster competition, and innovation, and discourage patent trolls, critics argue they create uncertainty, hinder software development, and potentially suppress genuine inventions. Striking the right balance between protecting innovative advancements and preventing abuse in the patent system remains a complex challenge for policymakers and the legal system as technology continues to evolve.
