We are a software company based in Europe making spreadsheet software.
We found a patent Enhanced editing of formulas in spreadsheets.
Actually suggesting functions while users edit a formula exists in almost all the major spreadsheet software, they use certain intelligence or algorithms that can well include machine learning.
We also plan to build the feature in our spreadsheet software.
So my question are:
- The patent belongs to Microsoft, why could other major spreadsheet software like Google Sheets still have this feature in their spreadsheet software?
- When building our feature, what could our company do to avoid future IP trouble with regard to this patent?
