Searching for old technologies that became publicly known more than 20 years ago.
 
The article 'Investigation for Infringement Prevention: Substituting with Old Technologies' by Yoshihide Tsunobuchi, patent attorney and PhD in Science, from the Intellectual Property Practice Information Lab's expert team, is indeed accurate.
When it comes to investigations for preventing infringement, there's a tendency to want to conduct exhaustive searches. However, by searching for old technologies that have been publicly known for more than 20 years, it's possible to find substitutes, significantly reducing the time, effort, and cost of the investigation. This is a useful approach.
