trying to open a new tab in the browser

thx. That worked. One thing, I'd like to open Google Patents in a new tab. How can I change that?

I tried this mod

<button class="btn btn-primary btn-lg" onclick="location.href='https://patents.google.com/','_blank'">Open Google Patents</button>

but it still opens in the same tab
