Has this patent been granted or only filed?
<p>I'm interested in implementing this technique in my app:</p>

<p><a href="https://encrypted.google.com/patents/CA2839098C?cl=en&amp;hl=en" rel="nofollow noreferrer">https://encrypted.google.com/patents/CA2839098C?cl=en&amp;hl=en</a></p>

<p>But from this page I can't figure out it the patent has only been filed, or actually granted too.</p>

<p>In the Google Patents listing you provided, the publication type says "Grant", so this appears to be a granted patent.</p>
