Assuming you&#x27;re not building &quot;this product&quot; under the cover of a corporation (in which you really do need a lawyer), you could always proceed pro se, which involves representing yourself.<p>Give caving to their demands a serious thought for a minute- have a disinterested party (or two) look over any agreements you&#x27;ve signed and the motion for injunction.  If they don&#x27;t completely take your side, odds are you&#x27;re going to lose at trial because you can&#x27;t convince a jury.  At that point you&#x27;d be right where you would be if you caved, only two years older with nothing to show for it and a great deal poorer.<p>This needs to be a cold, calculated financial decision on your part.  Even if you&#x27;re right and exonerated, does pursuing your product (versus some other product) pay enough to justify the additional costs?<p>To argue the matter on the principles is a privilege of the wealthy.
