1-800-CONTACTS also protests that there is nothing “scandalous” about its CEO visiting Ditto’s site to check out its product. We agree. There is certainly nothing wrong with keeping tabs on the competition. What we do think is scandalous, however, is what the company did next. After checking out Ditto’s product, 1-800-CONTACTS apparently went out and purchased a patent in order to sue its competitor.
