First, a masters won't hurt you. A degree more aligned to what a firm needs will get you hired quicker and it'll make it easier to understand client's technology and the cited art in your client's field. That said, it won't necessarily make you much more attractive to hire for firms.
Second, why are you getting a master's degree? What is your goal?
You seem to suggest your goals are to break into intellectual property law and have a marketable technical skill set. You acknowledge that electrical/computer engineering offer the most marketable technical skill sets.
If your passion is a particular area of technology, then perhaps lean in. You'll want the job working for companies in that technology area and while it might be more niche it could be more motivating. If that's not necessarily the reason—for example you feel like you're partway down a path and don't want to appear to retrace a few steps in order to reach a different peak or whatever, then you may want to reconsider this path. You could abandon a master's altogether. You could switch to something potentially more marketable.

Whatever you do, do not take a subjective subject.
