You never have the right to withhold knowledge. Thats what your company is paying you for. If in fact you are doing all the learning that will make you a valuable employee and whether or not your boss copies your work, he should realize how valuable you are and pay you accordingly. If you think you are being underpaid for your expanding skills feel free to take them elsewhere, but you are a professional. Your company is paying for your skills. You agreed to take the job for the stated money so give it your all.
