I received an email from a competitor claiming that I was infringing upon their copyright for their webpage. They used a program called COPYSCAPE to research similar wording as theirs in webpages. When I checked the wording with Copyscape, my website came up along with several others. This person has threatened to pursue this in court if I don`t remedy the phrases. They also accused me of plagerism. The infringement as they outlined to me was over my use of the words and phrases as follows:
"All items will be shipped within 24 to 72 hours of payment."
"All information you provide will be kept strictly confidential."
Mind you, these are just a couple of phrases sited in a long list of common business terms on my site. Can anyone claim ownership to copyright and exclusive rights to these commonly used phrases? I would appreciate any input, especially from a copyright lawyer or someone experienced in this matter. Thank you.
