Unless the confict involves a federal law, the California lawyer would have to obtain a Colorado lawyer to handle the matter. In the case of "intellectual property", if the matter involves a patent or copyright that is being violated, yes, that would be a federal issue that the California lawyer could handle (but to go to court in CO, he would need to have a local CO attorney involved). On the other hand, if the issues are contractual, even if "intellectual property", that would be a state issue that he could not handle since both parties are in Colorado (assuming there isn't language in the agreement requiring the agreement to be governed by CA law. You should consult with a local attorney who can assess the matter more fully than can be done via a site like this.
