Comparison of IPC and USPC classification systems in patent prior art searches

Proceedings of the 3rd international workshop on Patent information retrieval, 2010
Patent classification systems are used to help scrutinize patent applications for possible violations of the novelty and non-obviousness/inventive steps of a patentability test. There are several different patent classification systems in use today, each with a different underlying philosophy and approach.

Patents, Search of Prior Art, and Revelation of Information [PDF]

, 2007
This paper examines the strategic non-revelation of information by innovators when applying for patents. The lack of accessible prior art (i.e., an existing set of related inventions) may be responsible for the granting of questionable patents by examiners.

Catch-phrase based Document Representation for Improved Prior Art Search

Proceedings of the ACM India Joint International Conference on Data Science and Management of Data, 2019
With rising number of patent infringement cases, it is vital to both individual researchers and patent lawyers to search and assess existing patents similar to a patent before its filing. This paper proposes a query reduction based methodology that furnishes a set of ranked patent documents similar to a given input document.

PATATRAS: Retrieval Model Combination and Regression Models for Prior Art Search

2010
This paper presents PATATRAS (PATent and Article Tracking, Retrieval and AnalysiS), a system realized at the Humboldt University for the IP track of CLEF 2009. Our approach presents three main characteristics: 1. The usage of multiple retrieval models and term index definitions for the three languages considered in the present track producing ten ...

Query Generation Techniques for Patent Prior-Art Search in Multiple Languages

2013
Patent prior-art search is an necessary step to ensure that no previous similar disclosures were made before granting an patent. The task is to identify all relevant information which may invalidate the originality of a claim of a patent application. Using the whole patent or extracting high indicative terms to form a query reduces the search burden on

Prior art searching in the preparation of pharmaceutical patent applications

Drug Discovery Today, 1998
Profitability in the pharmaceutical industry depends upon market exclusivity, and exclusivity is largely based upon patent protection. Because patents are granted only for inventions that are new and nonobvious, it is essential that researchers know what is in the prior art before filing a patent application.

Using Classification Code Hierarchies for Patent Prior Art Searches

2011
Searches in patent collections to determine if a given patent application has related prior art patents is non-trivial and often requires extensive manpower. When time is constrained, an automatically generated, ranked list of prior art patents associated with a given patent application decreases search costs and improves search efficiency.
