Try the Public Pair search from the patent office. Search with this number: PCT/US08/65008

That number is the application number, and not the reference number (as you have given us in your question above). Data is listed from most recent to earilest.

  • 06-06-2008 Notification of Intntl. Appl. Number and Intntl. Filing

    This lets the applicant know that it has been assgined an Application number.

    However, since the information trail stops here, so it looks like the patent in question is still regarded as a application and not a "patent".

  • 06-06-2008 Notification Concerning Payment of Fees

    This means: filer was asked to pay fees associated with filing the patent.

  • 06-06-2008 Record Copy Mailed

    A copy of the patent application was mailed to the applicant.

  • 05-30-2008 Cleared by OIPE CSR

    That means: Approved by Office of Initial Patent Examination Customer Service Representative

  • 05-28-2008 Receipt Date

    According to the patent office that means:

    (a) Date of receipt and Priority Mail Express® date of deposit. Correspondence received in the Patent and Trademark Office is stamped with the date.

  • 05-28-2008 IFW Scan & PACR Auto Security

    Image File Wrapper -- an electronic version of a patent application.

    Patent advisory committee representative automatically checked for problems. There were none and the process continued.

  • 05-28-2008 Initial Exam Team nn

    This means: patent application revived.

  • If possible, could you please edit your answer here to include a bit more about how this information is useful in answering the asker's question? We'd like to start using this as a canonical question and answer to point users to when they ask about PCT applications, so we want to make sure this has enough information that someone with minimal knowledge in the field could benefit from it. It's up to you whether you'd like to do so, but I would appreciate it, and I'm sure other readers would as well! :) Commented Nov 17, 2015 at 1:35

  • Awesome! Thank you! I modified the formatting a bit, feel free to clean it up more if there's anything you see. Commented Nov 18, 2015 at 23:30

Alternately, and more simply, from the "A1" at the end you know it remains an application and has not been granted. "A" is called the "kind code" and tells you the status of the underlying patent.

See here, for a short page about WIPO kind codes: http://worldwide.espacenet.com/help?locale=en_EP&method=handleHelpTopic&topic=kindcodes

I actually think the USPTO has a better page (again referring to their use of WIPO kind codes) here: http://www.uspto.gov/learning-and-resources/support-centers/electronic-business-center/kind-codes-included-uspto-patent
