Microsoft�s patent?


If we put excel like functionality into your product, =(a1+b1) wont we be infringing Microsoft’s patent? Or has there patent expired?



Thank you for the post and your interest in Aspose.Cells. The following is a link to the patent in which you speak of:

Link to US patent site

The patent does not apply to the format in which the formula is entered, but rather the entire formula system within Excel. Therefore, the use of formulas in the mentioned manner would not be a violation of Microsoft's patent.

Please be sure to let me know if there is any other information I can provide and I will be more than glad to.
