Frequently Asked Questions

Why do I need a patent?

Patent protection can give you a 20 year monopoly to make, sell, use or otherwise trade in the claimed invention.  The obvious benefit behind this is that it gives the patent owner a competitive advantage in the marketplace. Find out more...

What is a trade mark?

Why should I do an IP search before investing in a new product, idea or brand?

What is the WWL?

Use the WWL to find contact details for patent attorney firms globally, and to look up the correct acronym to quote in your file reference when corresponding with them. As firms update their own contact information regularly, we recommend visiting the firm's website directly for the most current details.

Why use the unique acronyms?

For over 20 years, we've recommended moving away from "Our Ref" and "Your Ref" in email correspondence, as these labels can get swapped in a reply thread - especially when firms use similarly formatted file or matter numbers, making it hard to automatically match a communication to the right file. A unique acronym avoids this ambiguity. Pipers, for example, uses "Pipers Ref:" followed by our file reference, which lets our system automatically file all related incoming and outgoing correspondence electronically.

How do I get my firm added to the WWL, or request a different acronym?

Email webmaster@piperpat.com and we'll add your firm or update your listing. If you'd like to use an acronym different from the one we've suggested, let us know - we'll do our best to accommodate it, adjusting for any conflicts with acronyms already in use elsewhere in the list.

Do I need special software to use the acronym system?

No - it's simply a naming convention for your email subject line or reference field. Firms with automated filing systems (like Pipers') can use the acronym string to auto-sort correspondence, but you can also use it manually as a clearer alternative to "our ref/your ref."

How often is the WWL updated?

It's updated as firms submit changes or new listings via webmaster@piperpat.com. We recommend checking a firm's own website for the latest details, as the WWL reflects what's been submitted to us rather than being verified in real time.
