Changes to Patents Rules on 1 October 2016 and 6 April 2017

Published 1 September 2016


The government conducted a public consultation between February and April 2016, seeking views on a package of proposed changes to the Patents Rules 2007. These rules govern the detailed requirements which must be met for a patent to be granted. They also set out the procedures which must be followed when applying for a patent or making changes to a granted patent.

In light of the responses received, the government will take forward the proposed changes, adjusted as appropriate in light of comments received. The changes are being made to increase legal certainty, make procedures more flexible, and reduce administrative burdens for patent applicants and owners.

This guidance summarises the changes and their impact on businesses and individuals who use or have an interest in the patents system.

Changes taking place on 1 October 2016

Notification of intention to grant

On 1 October 2016, the Intellectual Property Office (IPO) will start to issue a new notification of intention to grant. This letter will inform a patent applicant that their application meets all the requirements for grant of a patent. It will also state that the patent application will be sent for grant on or after a certain date. No further action will be required from the applicant in relation to the patent application in question. However, the letter will provide applicants with a clear picture of the time left to take any other action they wish before grant. In particular, there will be a clear timeframe within which to file any divisional patent application.

In the majority of cases the letter will give one month’s advance notice of grant. Two months’ notice will be provided if the letter is issued at the first examination, as is currently the case. (This two months’ notice is required by the Patents Rules. It ensures the applicant has an opportunity to make voluntary amendments to their patent application or file a divisional application.) The introduction of these notifications will end the practice of “foreshadowing” divisional applications. (That is to say, the practice of applicants raising the possibility of filing a divisional application, and asking for time to do so before a patent is granted.) Instead, from 1 October, applicants will be guaranteed a period to file such applications. They will know that the main application has met all the requirements for grant, but will have time before its actual grant.

“Intention to grant” notifications will be issued from 1 October 2016 onwards. The introduction of this change in practice means that very few patents will be granted during October 2016. Patents granted on Tuesday 4 October 2016 will be the last patents to be granted with no advance notification of grant.

Notifications of intention to grant will be issued on applications which have met all the requirements for grant of a patent by the compliance date. The notifications will form a report under section 18(4) of the Patents Act. They will be publicly available on the IPO’s online patent information and document inspection service (Ipsum).

In order to introduce this change, rule 19 of the Patents Rules will be amended on 1 October 2016. It will allow divisional applications to be filed after a notification of intention to grant has been issued. The requirement that divisional applications must be filed at least three months before the compliance date will be retained. It will also continue to be the case that divisional applications must be filed before grant of the earlier application.

An explanation of the changes to existing rule 19 are set out below.

  • Rule 19(1) has been retained
  • Rule 19(2) has been retained, but is now rule 19(2)(a)
  • Rules 19(3), 19(4) and 19(5) have been merged. The deadlines for filing a divisional application were based upon whether the earlier application had been found to meet the requirements for grant. These deadlines have been removed. New rule 19(2)(b) now provides a single deadline of three months before the compliance date of the earlier application. The Patents Act itself continues to require that any divisional application is filed before the earlier application is granted
  • Rule 19(6) has been retained, as new rule 19(3)
  • Rule 19(7) is deleted as it is now redundant

Simplifying the time period for requesting reinstatement

Where a patent application is terminated because the applicant unintentionally failed to meet a deadline, it is possible to request reinstatement of the application. However the current deadline for requesting reinstatement is complicated to calculate and causes confusion. The deadline will change on 1 October 2016. Applicants will simply have 12 months from termination of their patent application to request reinstatement. The new rule will be applicable to all terminated patent applications from 1 October 2016 onwards. This means that, from 1 October 2016, reinstatement may be requested in relation to any patent applications that have previously been terminated as long as no more than 12 months has passed since the date of termination. It will remain possible for the IPO to impose third-party terms when reinstating a patent application. These allow anyone who has proceeded to make or use the invention, on the basis of the application being terminated, to continue to do so.

Allowing extensions to the period for providing an address for service

All patent applicants must provide an address for service in the European Economic Area or Channel Islands. This enables the IPO or other parties to contact them about their patent application or patent. Currently the period for providing this address is two months and the period is not extendable. From 1 October 2016 applicants will be able to request a two-month extension to this period. This can be done by filing Patents Form 52 accompanied by the relevant fee (currently £135). The request for an extension must be made no more than two months after the period has expired.

Relaxing the requirements for formal drawings

On 1 October 2016 the legislative requirements relating to technical drawings included in patent applications will be relaxed. They will allow shading in drawings, providing the shading does not obscure other parts of the drawing. It will also be possible to include black and white photographs, providing they are clear and capable of reproduction. This will bring the legislation more clearly into line with current IPO practice, providing clarity and legal certainty for patent applicants. The IPO will continue to reject drawings and photographs if they are not suitable for publication.

Amending international patent applications upon entry to the UK national phase

International patent applications are initially processed by the World Intellectual Property Organisation (WIPO) under the Patent Cooperation Treaty (PCT). The applicant can then choose to continue the patent application process in individual jurisdictions. This part of the process is known as the “national phase”. In the UK national phase, applicants can amend their patent application voluntarily in response to reports made by the international authorities. This deals efficiently with issues raised by the international authorities, speeding up the application process as a result.

The change on 1 October 2016 will clarify when an applicant can amend their international patent application which enters the UK national phase. The first scenario is where an international search report (ISR) has been issued by the time the application enters the UK national phase. Here, the applicant can amend voluntarily from the time of UK national phase entry up until the first UK examination report is issued. The second scenario is where no ISR has been issued by the time the application enters the UK national phase. Here, the applicant can amend voluntarily from the date of issue of the UK search report or the ISR (whichever is first). Again, the cut-off is the date of issue of the first UK examination report. This rule change will bring the legislation more clearly into line with current IPO practice. It will also provide clarity and legal certainty for patent applicants. It will remain possible to amend all patent applications voluntarily in response to the first examination report, and at other times with the IPO’s permission.

Clarifying requirements concerning changes of names and addresses

This change concerns name or address details registered with the IPO in relation to a patent application or a patent. The law is currently unclear about what requirements apply when a customer wishes to update this information. Such an update will be necessary when the information was previously correct but there is then a change in situation. An example may be a house move or a change of name. The legislation is being clarified to make clear that the procedure relating to corrections of names and addresses (used when there was an error in the information recorded) also applies where there has been a change in circumstances. Patents Form 20 will continue to be the form which is used to correct or update a name or address. The form will be revised on 1 October 2016 to include a new tick box. This will allow the user to specify whether they wish to correct an error or to update information held by the IPO.

Advertising amendments made during proceedings

This change concerns the situation where the validity of a granted patent is challenged during infringement or revocation proceedings. The patent proprietor may request to amend the patent in order to avoid revocation. The legislation is clarified on 1 October 2016 to reflect that, under the Patents Act, the IPO has discretion over whether to advertise such amendments. In practice the only amendments not advertised would be those which are so insignificant that no-one could be expected to want to oppose them. Amendments to a patent which are proposed to avoid revocation are very unlikely to be insignificant. It follows that these amendments will be advertised. Guidance such as the Manual of Patent Practice will set out the factors the IPO will consider before deciding whether to advertise or not.

Removing certain requirements for multiple copies of documents

From 1 October 2016 it will no longer be necessary to provide duplicate copies of Patents Form 51. This form is used to appoint or change a patent agent.

It will also no longer be necessary to file an international patent application in triplicate, when using the IPO as a receiving office under the Patent Cooperation Treaty.

Changes taking place on 6 April 2017

Allowability of omnibus claims

Patent claims define the scope of the monopoly provided by the patent by setting out the technical features present in the invention. Sometimes claims are drafted in such manner as to refer generally to the description or drawings included in the patent application. Such claims do not state the technical features of the invention claimed and are known as “omnibus claims”. Understanding these claims can be difficult and can lead to a lack of clarity about the scope of protection provided by the patent. This can make it difficult for businesses to know if they are likely to infringe a competitor’s patent.

From 6 April 2017 it will generally no longer be allowable to include omnibus claims in UK patent applications. They will only be allowed if the technical features of the invention cannot otherwise be clearly and concisely defined using words, a mathematical or chemical formula or any other written means. From 6 April 2017 onwards, patent examiners will raise objections to any omnibus claims present in pending patent applications. But they will not do so if the patent application has a compliance period which expires before 6 April 2017.

Furthermore, from 6 April 2017 it will no longer be possible to amend a granted patent to insert an omnibus claim. However the presence of an omnibus claim in a granted patent will not be a ground for revocation. Any granted patents including such claims will remain valid.

Limiting the use of omnibus claims will increase legal certainty for businesses looking to determine whether they can operate in a particular technology area. It will bring UK requirements into line with the requirements of the European Patent Convention (EPC) and the international Patent Cooperation Treaty (PCT).

Address used to receive renewal reminders

Currently, patent holders must notify the IPO annually of the address to which renewal payment reminders are sent (where it differs from the registered address for service). From 6 April 2017, it will no longer be necessary to make this annual notification. Instead, the IPO will continue to use the address previously provided, until it is cancelled or updated by the patent holder. This change will reduce an administrative burden for patent holders. It will also provide them with an increased opportunity to use our online renewal services. These services are not available if an address is being notified at the same time as payment of the renewal fee.

Further guidance on this change is available at Patents renewal reminders – change taking place on 6 April 2017.
