well-defined lines and strokes to permit satisfactory reproduction; 
(b) cross-sections shall be indicated by hatching which does not impede the clear reading 
of the reference signs and leading lines; 
(c) the scale of the drawings and the distinctness of their graphical execution shall be such 
that a photographic reproduction with a linear reduction in size to two-thirds would 
enable all details to be distinguished without difficulty. If, as an exception, the scale 
is given on a drawing, it shall be represented graphically;

The summary shall indicate the technical field to which the invention belongs and be drafted in 
a way which allows a clear understanding of the technical problem to which the invention 
relates, the gist of the solution to that problem through the invention and the principal use or 
uses of the invention. Where appropriate, the abstract shall also contain the chemical formula 
which, among those contained in the specification, best characterises the invention. It shall not 
contain statements on the alleged merits or value of the invention or on its speculative 
application.

figure or, exceptionally, the figures of the drawings which he suggests should accompany the 
abstract when published. The comptroller may decide to publish one or more other figures if 
he considers that they better characterise the invention. Each main feature mentioned in the 
abstract and illustrated by a drawing shall be followed by the reference sign used in that 
drawing. 
(5) The abstract shall be so drafted that it constitutes an efficient instrument for the purposes 
of searching in the particular technical field, in particular by making it possible to assess 
whether there is a need to consult the specification itself.

a single inventive concept for the purposes of the Act. 
(2) In this rule, "special technical features" means those technical features which define a 
contribution which each of the claimed inventions, considered as a whole, makes over the 
prior art.

application shall respectively relate only to the matter for which protection is sought by that 
application. However, when it is necessary for an application to describe the matter for which

is desired to make a declaration specifying for the purposes of section 5(2) an earlier relevant 
application and the period of twelve months immediately following the date of filing the earlier 
relevant application ends on a day which is an excluded day for the purposes of section 120,

the earlier relevant application and the day on which the declaration is made in or in connection 
with the application in suit. 
(4) Where it is desired to make such a declaration and the said period of twelve months 
immediately following the date offiling the earlier relevant application ends on a day certified 
under paragraph (1) above as being one on which there is an interruption, the period shall, if 
the declaration is made on the first day following the end of the interruption, be altered so as 
to include both the day of filing of the earlier relevant application and the day on which the 
declaration is made in or in connection with the application in suit.

falling within paragraph (a), (b) or (c) of section 2(4); or 
(c) the period of twelve months referred to in paragraph (3) above,

day of the receipt by the addressee of the notice, application or other document

is not an excluded day); 
(ii) determine that the period of six months referred to in subparagraph (b) above 
shall be altered so that it begins on the day of the disclosure and ends on the day 
of receipt by the Patent Office of the application for the patent (or, if the day of 
such receipt is an excluded day, on the first following day which is not an 
excluded day); or 
(iii) determine that the period of twelve months referred to in paragraph (3) above 
shall be altered so as to include both the day of filing of the earlier relevant

(b) which cannot be described in the specification in such a manner as to enable the invention to be 
performed by a person skilled in the art, 
shall, in relation to the micro-organism itself, be treated for the purposes of the Act as disclosing the 
invention in such a manner only if one of the conditions set out in subparagraph (2) below is satisfied. 
(2) The conditions referred to in subparagraph (1) above are-
(a) a condition that,-
(i) not later than the date offiling of the application, a culture of the micro-organism has been

(4) The giving of the information specified in subparagraph (2)(a)(ii) above shall constitute the 
unreserved and irrevocable consent of the applicant to the depositary institution with which a culture

EXPLANATORY NOTE 
(This note is not part of the Rules) 
These Rules consolidate, with modifications, the Patents Rules 1990 as amended. In addition 
to minor and drafting amendments, they make the following changes of substance-
(a) the forms prescribed under the Patents Act 1977 ("the Act") have been reduced in 
number and modified (rule 4 and Schedule 1); 
(b) revised provision is made in relation to declarations of priority in the case of new 
applications under section 15(4) of the Act, and in relation to the documents to be 
provided in connection with declarations of priority (rule 6); 
(c) revised provision is made in respect of applications to which all parties have consented 
as to who should be mentioned as the inventor in any patent (rule 14); 
(d) additional provision is made for the voluntary amendment of the description, claims 
or drawings (rule 36); 
(e) throughout the Rules, provision is made requiring applications and requests to be 
advertised only in the Journal and uniform procedures are prescribed in respect of 
opposition to any matter (rules 40,65, 71, 78 and 91); 
(t) revised provision is made in respect of applications to register transactions, 
instruments and events (rule 46); 
(g) the provisions concerning applications to settle licences of right have been clarified 
(rule 62); 
(h) specific provision is made prescribing periods in respect of those international 
applications for a patent which are to be treated as applications for a patent under the 
Act and which applications are to proceed earlier in the national phase (rule 85(7 A»; 
(i) the United Kingdom Patent Office no longer carries out international preliminary 
examinations under the Patent Co-operation Treaty and the relevant Rules have been 
omitted accordingly (formerly rules 120 and 121). 
A compliance cost assessment is available, copies of which have been placed in the libraries of 
both Houses of Parliament. Copies of the assessment are also available from the Intellectual 
Property Policy Directorate of the Patent Office, Room 3/13, HazEtt House, 45 Southampton 
Buildings, London WC2A lAR. 
The Rules take effect on 4th September 1995. 
At the date of making these Rules the address of the Patent Office is Cardiff Road, Newport, Gwent 
NP9 lRH and 25 Southampton Buildings. London WC2A lAY.
