Problems with the use of Keywords only

Problems ExamplesDifferences in American and British English

Tire (American) vs Tyre (British)

Poor translation from foreign patents

Accuracy of machine translation is at most 60-70%

Too many synonymsMethod, Mechanism, Means, Process have similar meanings

Novel terminologiesE.g. Mousetrap = Rodent Extermination Device

Different ways of spelling company names

Sony Electronics or Sony Corporation

Ways to overcome

• Technical Dictionary

• Technical Thesaurus– INSPEC (Electrical Engineering Terminologies)

– MESH (medical subjects)

For rapidly developing technologies, an update of the IPC classification every 5 years maybe inadequate.

Obsolete ClassificationSome databases may not update their old classification even

Minimal ClassificationLack of classification in CanadianPatents
