Initial requirements

To secure a filing date on your behalf, we will require the following information and documentation. All applications must be made in English:

• Copy of patent specification, including description and (usually) drawings
• Full name and address of all applicants, including nationality and (if applicable) State of Incorporation
• Details of any priority claim, if appropriate, including at least the filing country and filing date and preferably the serial number

Post-filing requirements

The following material may be submitted after filing:

• Name and address of each inventor, including details of how rights are transferred to the applicants(s) by the inventor(s). For example, this may be 'by assignment dated…' or 'by virtue of a contract of employment'
• A certified copy of the Priority Document
• Formal Drawings to replace any informal drawings initially filed

Note: For a UK, European or international application, we do not normally require forms to be signed, either by the applicant(s) or by the inventor(s).
