Flywheel patent search

Post by slakshmi » Mon Jun 12, 2017 2:36 pm

Hello,

I am creating a query for finding all patents relevant to flywheels, including patents for flywheels as component in a larger system, and peripheral components in flywheel systems. So far I have used the following search terms to find IPC classifications relevant to my search:

Search keywords:
"flywheel"
"bearing"
"housing"
"shaft"

I got lists of over a hundred classifications for each keyword search. For the latter three keywords, I filter patents by searching for the following keywords in the title and/or abstract:

Filter keywords:
"flywheel"
"inertia"
"energy storage"
"kinetic"

The full list of classes using this approach is long - over 100 line items. There are several false positives generated with this method, but this hopefully ensures there are fewer false negatives.

My questions are:
1. Are there any keywords I should add to [either] list to make it more comprehensive?
2. Is there a simpler but still robust approach?
