Why a prior art search matters for mechanical
Mechanical fields have more than a century of accumulated art, so obviousness combinations are the main hurdle and a search is how you anticipate them. It also helps you claim the specific structure that is genuinely new.
- Examiners readily combine references, so distinguishing on a specific structural cooperation matters.
- Old patents never expire as prior art; a relevant reference can be decades old.
- Drawings often carry as much weight as claims when comparing structures.
