2. Roadmap INTRODUCTION TO PATENT SEARCHES ORBIT Patent searches portal and IP Business Intelligence SEARCH EXAMPLES 2

3. The role of patents Protection and economic exploitation of the inventions Sources of information: technical, scientific, business publicly available 3

4. Importance of patent information Volume Content Accessibility First account 4

5. Use of patent information Survey state of the art competitors’ activities Identify solutions to technical problems licensing opportunities Avoid duplication of R&D efforts infringements 5

6. Patent databases Worldwide bibliographic Search fields: bibliographic data, title and abstract (as published by the inventor or enriched by the producer) Full text Search fields: bibliographic data, title, abstract (as published by the inventor), description, claims 6

7. Operators Bibliographic data Keywords Search fields Classification 7

25. Key content Extracted from US, EP, WO, full-text in English Identify key sentences describing patent object, advantages and drawbacks, independent claims Uses morpho-syntactic analysis to spot important sentences Good compromise between conciseness of bibliographic abstracts and full text

26. FamPat Concepts – Field available in FamPat – Extracted from US, EP, WO, full-text in English – The Concept Field contains keywords and multiword phrases that can be used in searching, browsing and in analysing

27. Concept extraction Main idea: extract concepts rather than words as a semantic model of patent documents, weight concepts according to sentence type To deal with large volume we need to do this upfront when loading the data

28. Semantic concept tagging « noun phrases » identification – Part-of-speech + stemming – Verb Suppression, some adjectives – Suppress typical“patent” terminology « preferred embodiment », « skilled artisan » …. – Syntactic normalization : « surface of screens »  « screen surface » Relevance score computation, based on: – Field, key sentence morpho-syntactic detection, and number of occurrences

29. Concept extraction example The invention relates generally to molecular level cleaning of parts by vapor degreasing. More particularly, the invention relates to a solvent mixture comprising n-propyl bromide, a [mixture of low boiling solvents] and, … The solvent mixture of the invention is non- flammable, non-corrosive, non-hazardous, and has a low ozone depletion potential.

30. Normalization examples the heat conductivity the conduction of heat heat conductivity heat conduction HEAT CONDUCTION the user of the cellular telephone cellular phone users a user of a mobile telephone any mobile phone users their user mobile telephones MOBILE PHONE USER

31. Concepts Each key concept is “scored” Score calculation based on: – Occurrences of the concept in the doc – Fields where the concepts appear – Frequency of the multiword concept in the database – Frequency of the concept words in the database – Non-linear formula (QUESTEL Lingway trade secret) – Normalized to 100 (high score)
