Use Of AI In Prior Art Searches By The Polish Patent Office.

1. How AI is used in Prior Art Searches (UPRP Context)

The Polish Patent Office uses AI indirectly through:

(A) Semantic Search Engines

  • AI-based keyword expansion (synonyms, contextual meaning)
  • Helps identify prior art beyond exact keyword matches

(B) Classification AI (CPC / IPC automation)

  • Machine learning assigns patent classifications
  • Improves accuracy in technical grouping

(C) Image Recognition AI

  • Used in design patent searches (shapes, logos, industrial designs)

(D) Natural Language Processing (NLP)

  • Reads patent abstracts and maps conceptual similarity

(E) EPO Integrated Tools

UPRP examiners rely heavily on:

  • European Patent Office databases
  • AI-enhanced tools like classification assistants and translation systems

2. Legal Foundation for AI-Assisted Prior Art Searches

Under the European Patent Convention (EPC):

  • Article 54 defines novelty
  • Article 56 defines inventive step
  • Prior art must be globally assessed

This requires increasingly powerful search tools, which AI supports.

3. Key Case Law Supporting AI-Type Search Logic

Even though courts do not directly rule on “AI tools in patent search,” they define how prior art must be interpreted, which justifies AI usage.

1. T 258/03 Hitachi / Auction Method

Facts:

The case involved a computer-implemented auction method and whether it was patentable.

Legal Issue:

How should prior art be interpreted for mixed technical and business features?

Decision:

The Board held:

  • Focus must be on technical contribution
  • Search must consider functional similarity, not literal wording

AI Relevance:

This decision supports AI-based semantic search:

  • AI can detect conceptual similarity beyond keywords
  • Mirrors how examiners interpret prior art today (including UPRP practice)

2. T 641/00 COMVIK

Facts:

Concerned a method involving technical and non-technical features.

Legal Principle (COMVIK approach):

  • Only technical features contribute to inventive step
  • Non-technical aspects are ignored in evaluation

AI Relevance:

AI prior art systems now:

  • Filter irrelevant non-technical results
  • Focus on technical features in classification

👉 This is the legal foundation for AI “relevance scoring” in patent search engines used in Europe and indirectly in Poland.

3. T 1242/04 Micron Technology

Facts:

Patent relating to semiconductor technology and data storage.

Issue:

Whether prior art search must include non-obvious combinations of documents.

Decision:

The Board ruled:

  • Examiners must consider implicit disclosures
  • Prior art is not limited to explicit text

AI Relevance:

AI tools now:

  • Combine multiple documents
  • Detect hidden relationships between technical disclosures

👉 This is exactly what machine learning-based prior art systems do today in UPRP-supported workflows.

4. T 1642/07 ZIMMER

Facts:

Concerns medical device patent validity and prior art interpretation.

Issue:

Whether prior art must be interpreted as it would be by a skilled person.

Decision:

  • Prior art must be assessed through the lens of the “person skilled in the art”
  • Not literal interpretation

AI Relevance:

AI systems in patent offices:

  • Simulate “skilled person reasoning”
  • Use NLP models trained on technical literature

👉 This case supports AI-driven contextual interpretation in search results.

5. T 0301/87 General Electric

Facts:

Concerns novelty of electrical engineering invention.

Issue:

How broad prior art interpretation should be.

Decision:

  • Even implicit teachings in prior documents can destroy novelty
  • Prior art must be read broadly and technically

AI Relevance:

AI-powered prior art systems:

  • Expand queries using semantic networks
  • Detect implicit disclosures across multiple patents

👉 This case justifies AI “expansion search logic”.

4. How These Cases Influence the Polish Patent Office (UPRP)

Although these are EPO cases, the UPRP follows them due to harmonization under EPC principles.

Practical impact:

(A) AI improves novelty detection

  • Detects hidden similarities (T 0301/87 principle)

(B) AI supports inventive step analysis

  • Filters technical vs non-technical features (COMVIK rule)

(C) AI enables semantic prior art search

  • Based on Hitachi case reasoning

(D) AI assists examiner reasoning simulation

  • Based on “skilled person” doctrine (Zimmer case)

(E) AI enables document clustering

  • Based on implicit disclosure principles (Micron case)

5. Example: AI Prior Art Search Workflow at UPRP

When examining a patent application like a Neural Creative Studios AI algorithm:

  1. AI extracts:
    • Technical features (e.g., neural network architecture)
  2. System expands query:
    • Synonyms: “deep learning”, “generative model”, “GAN”
  3. AI searches:
    • EPO + global databases
  4. Machine learning ranks results:
    • Based on semantic similarity
  5. Examiner verifies:
    • Using EPC legal standards (cases above)

6. Conclusion

The Polish Patent Office does not operate AI in isolation; instead, it integrates AI-driven prior art search tools within a European legal framework shaped by EPO case law.

The key takeaway from jurisprudence is:

  • Prior art must be interpreted broadly, contextually, and technically
  • AI is legally justified because it improves:
    • Semantic understanding
    • Implicit disclosure detection
    • Technical relevance filtering

For a modern entity like Neural Creative Studios, this means:

  • AI-related patents face highly sophisticated prior art searches
  • Even non-obvious conceptual similarities can be detected by AI systems used in Europe, including Poland
