Patentability Search: 15 Key FAQs & Process Explained

6. What Advanced Search Techniques are used for Complex Chemical or Pharmaceutical Patentability Searches?

Chemical and pharmaceutical patents often involve highly specialized technologies, and patentability searches in these areas require advanced techniques to identify the nuances of molecular structures or chemical compositions.

• Chemical Structure Search: Databases like CAS (Chemical Abstracts Service) provide the ability to search based on chemical structures, rather than just keywords. These searches are essential when dealing with pharmaceutical compounds or biotech innovations where small molecular differences can make a significant impact on patentability.

• Sequence Search: For biotechnology patents, sequence-based searching is employed, particularly for nucleic acids and proteins. This involves searching patent databases using genetic sequence data or protein sequences, which is far more precise than a traditional text-based search.

• Bioinformatics Tools: Leveraging bioinformatics platforms that can analyze complex biological and chemical data in the context of patent claims is essential. This approach helps identify prior art based on molecular characteristics that may not be immediately obvious from patent texts alone. 

7. How Are Inventive Step and Non-Obviousness Evaluated in Patentability Searches?

Evaluating the inventive step (also known as non-obviousness) is one of the most critical aspects of a patentability search. The concept refers to whether the invention would have been obvious to someone skilled in the field at the time of filing, based on prior art.

• Patent Examiner’s Perspective: Patent examiners typically apply a “problem-solution” approach to assess inventive steps. The search identifies prior art that addresses similar problems, and the examiner looks for the specific inventive leap made by the applicant. This assessment is highly subjective and can vary based on jurisdiction.

• Search Strategy: During a patentability search, a nuanced approach is taken to identify whether the invention would have been obvious, given the prior art. This includes assessing whether the combination of existing patents or technologies would have led to the claimed invention.

• Complex Fields: In areas like AI, machine learning, or biotechnology, evaluating inventive steps becomes more difficult due to the rapid evolution of these technologies and the challenge of identifying clear distinctions in innovation. Expert opinions from industry professionals are often crucial in assessing the inventive step. 

8. How Are Patentability Searches Different for Emerging Technologies?

Emerging technologies such as quantum computing, blockchain, and artificial intelligence present unique challenges for patentability searches:

• Rapid Innovation Cycles: These fields evolve quickly, and patent landscapes may shift dramatically within a few years. A patentability search in such sectors requires up-to-date, real-time data from cutting-edge research publications and ongoing patent filings.

• Novel Concepts: Emerging technologies often deal with concepts that are abstract or theoretical in nature, making it harder to identify equivalent prior art in traditional patent databases. Using non-patent literature (scientific journals, white papers, research reports) becomes more critical to understand the technology landscape.

• Cross-Disciplinary Searches: Many emerging technologies are interdisciplinary (e.g., combining physics, computer science, and engineering), so the search strategy must span across various technical fields. These searches require expertise in multiple disciplines to ensure comprehensive coverage. 

9. How Does a Patentability Search Handle the Subject Matter Eligibility of an Invention?

Subject matter eligibility refers to whether an invention falls within the categories that can be patented, such as machines, manufactures, compositions of matter, and processes. 

The requirements for subject matter eligibility vary by jurisdiction, with some areas like the U.S. using the Alice/Mayo test for abstract ideas and software-related inventions.

• Search Focus: When conducting a patentability search, patentability assessors will not only look for novelty and inventive step but also check whether the invention’s subject matter fits the legal framework for patent eligibility in the relevant jurisdiction.

• Challenges: Particularly for abstract innovations like software algorithms or business methods, it can be challenging to determine eligibility based solely on prior art. The search may include looking for similar patent claims, rejections, or legal precedents to understand how similar inventions were evaluated for eligibility.

• Global Variations: Different patent offices (e.g., USPTO, EPO, JPO) may have differing standards for subject matter eligibility, particularly concerning fields like biotechnology and software, which necessitate region-specific search strategies. 

10. What Are the Limitations of a Patentability Search?

While patentability searches are valuable tools, they are not foolproof. There are several limitations inherent in the process:

• Scope of Search: A search can only be as thorough as the databases used. If relevant patents or publications are not indexed in commonly used patent databases, they could be missed.

• Language Barriers: Many patents and scientific papers are published in different languages. Non-English documents, particularly those from regions like Japan, China, or Russia, might be excluded from the search or require specialized translation tools for effective review.

• Incomplete Databases: Patent databases are updated regularly, but they may not always reflect the most recent filings or publications. This gap can pose a risk in fast-developing fields.

• Human Error and Interpretation: Patent searches often rely on human judgment to interpret ambiguous or complex claims. Even with advanced tools, interpreting patents and classifying prior art requires significant expertise.

Despite these limitations, a well-conducted patentability search provides a highly informative preliminary assessment of an invention’s chances of being patented.
