Why search Dialog when the Internet is free? • Search multiple databases at same time, on a similar search standard and interface

• In case of literature one can remove duplicates• In case of patents one can identify duplicates• All of our data are from refered, peer-reviewed or government/accepted publishers.• Most patent offices around the world use Dialog. Why would they, when they are the source

of the information themselves? • We take great pains to keep our files as up to date as possible• Add as much information as we can

- like enhanced titles for patents,- patent assignee numbers and codes- adding the years to the end of US application numbers so that users can find them

• Our goal is to make the data as useable as possible, while government agencies have only to put the data out there.

• A search on Dialog can take less than an hour whereas a similar search on the Internet, covering the same sources could take much longer • Almost every government free file has a disclaimer that states the data is not to be used to serious research. • Customer service ( Have you tried asking a patent office for help with a search!)

What is Prior Art?

The general level of knowledge in the area of expertise involved with an invention that existed prior to, or is available at the time of, the invention.

– The Intellectual Property Law Dictionary

12

What is Prior Art? • A search to find whether the “inventive step” within the patent application is

already in the public domain• This is done by searching the “state of the art” (i.e., comparing what is already known in the industry with the patent application)• Relevant prior art is the benchmark used to determine whether an invention

is really “inventive” (novel and non-obvious)

Prior art includes:• Any relevant description or discussion of the invention’s essential characteristics in prior printed publication anywhere in the world in any language that was made public before the invention was conceived of• Any relevant printed publication prepared by the inventor and published more than one year prior to the filing date of the patent application• Any relevant foreign or U.S. patent issued before the inventor conceived of the invention for which a patent is being sought, or any U.S. patent application made prior to such conception

13

Problems in searching Prior Art?

Titles: General & vagueAbstracts: Not summarising, only a rewritten claimSpecification: Jargons, acronyms, word order reversal aboundClaims: Several Claims for a single patent - Broad and more specific ones

PATENTS WRITTEN TO BE DEFENDED IN COURT, NOT FOR EASE OF SEARCHING

14

Searching Prior Art

• Patents are written by patent attorneys to obscure the invention• Attorneys write to get as wide protection as possible and be able to defend the patent in court. They do not write for searchers.• Search Techniques:

-- Include as many synonyms as possible in separate sets-- Use the “N” connector (e.g., (5n), (10n))

a red car could be described as “A vehicle having the colour red”-- Avoid combining OR and AND operators in the same SELECT statement-- Use verbs as nouns and vice versa-- Use both technical terms, and “normal” English-- Use indexing-- Use your imagination—don’t limit yourself in words or sources
