OP is deferring the T6 (code for CCN and not YHS) acceptance, not rejecting it. He or she still has the option of attending next year, if PTO doesn't work out. Indeed, he or she might be close enough to YHS that with a better LSAT or luck, there might be shot at those schools next year.
In my opinion, even if it was a YHS acceptance, it's better to defer in this case because OP has no full time work experience. Having a real job and paying bills from your paycheck can change your perspective on what prestige, career, free time, and debt really means. $250,000 of school debt is an abstract number until you try to live on $4,000 a month and realize what servicing a $2,500/month debt would mean.
Patent examining isn't for everyone and there are more prestigious jobs for the pre-law track. If I was OP, I'd try for an engineering or research job because that's I've been trained for and I should give it a go first before turning to other paths. However, it's a tough job market even for extremely qualified grads and a PTO job in hand might a better option than the actually available alternatives. An examiner job would give OP more options and experiences, which allow him or her to make a more informed decision a year from now. That's far better than blowing through to law school, saddled to a life changing amount of debt and a more limited set of career options.
OP - Horsechute's comments have their merits, but he is extremely anti-patent office. How happy you'll be at the PTO depends largely on your SPE and art area, and somewhat on your personality and work habits. Some people who have years of work and academic experience are very happy there, while other people leave very quickly. If you do go to the PTO, go with an open mind.
