Improvement of a patent in force

[Mariem]

Can I improve an invention that is currently patented (patent in force)?
For example, I am creating a dating mobile/website app, so I base it on certain features that are currently patented by another dating app. However, I add improvements and changes to these protected features.
Is that legal or would it be considered as an infringement of the patent?
Thank you in advance.

It is impossible to say without spending a lot of time and money researching their patents and your idea in detail.  Even after spending all that time and money it would still just be a "guess" or estimate on how likely you may be infringing their work.

In general you cannot make or sell a product that is still using a patented process or component even if you think are are improving on it.

*The type of opinion you are looking for is called a "freedom to operate" legal opinion and is not something we provide.  You should really speak with a patent attorney with this type of experience and registered in your area.
