Defectos en la hoja de dibujos

1. Formas gráficas de presentación consideradas como dibujos. :

1.1 Dibujos técnicos

Se considera dibujos todo tipo de dibujos técnicos; incluyen, por ejemplo, perspectivas, vistas explosionadas y secciones, detalles en una escala diferentes, etc. Los dibujos incluyen "diagramas de flujo", bajo los cuales se subsumen diagramas funcionales y representaciones gráficas de un fenómeno determinado que expresa la relación entre dos o más magnitudes.

1.2 Fotografías

Se permiten cuando sea imposible presentar en un dibujo lo que tiene que ser mostrado y con tal de que sean directamente reproducibles y cumplan los requisitos aplicables a los dibujos (es decir, tamaño y márgenes). Se aceptan las fotosgrafías en color. La OEPM se reserva la posibilidad de publicarlas en blanco y negro o requerir nuevas fotos si la calidad de reproducción no es suficiente. Las fotografías serán numeradas como los dibujos y descritas brevemente en la descripción.

2. Representación de los dibujos

2.1 Agrupamiento de dibujos

Todos los dibujos deben estar agrupados juntos en hojas específicamente dedicadas a representar los dibujos y no pueden ser incluidas en la descripción o reivindicaciones.

2.2 Reproducibilidad de los dibujos

Los dibujos deben presentarse de tal forma que permitan la reproducción directa tras el escaneo. Cada hoja debe estar razonablemente exenta de tachaduras o efectos del borrado que impidan la reproducibilidad o el escaneo.

Las correcciones deben ser permanentes, de tal forma que no den lugar a duda alguna. Se pueden usar productos correctores siempre que sean indelebles. Las hojas sólo pueden ser unidas con elementos de unión fácilmente removibles (clips, grapas).

3. Presentación de las hojas de dibujos

3.1 Numeración de las hojas de dibujos

Todas las hojas deben numerarse consecutivamente con números arábigos (1,2,3,...). La numeración de las hojas de los dibujos, será independiente, empezando por la hoja 1.

4. Disposición general de los dibujos

4.1 Numeración de los dibujos

Los diferentes dibujos deben ser numerados consecutivamente con numeración arábiga (1,2,3,...), independientemente dle número de hojas.

Esta numeración deberá ser precedida por la abreviatura "FIG". Where a single figure is sufficient to illustrate the invention, it should not be numbered and the abbreviation "FIG" must not appear. Rule 46(2)(d) also applies to numbers and letters identifying the figures, i.e. they must be simple and clear and may not be used in association with brackets, circles, or inverted commas. They should also be larger than the numbers used for reference signs.

An exception to Rule 46(2)(h) referred to above may be permitted only as regards partial figures intended to form one whole figure, irrespective of whether they appear on one or several sheets. In this case the whole figure may be identified by the same number followed by a capital letter (e.g. FIG 7A, FIG 7B).

5.3 Whole figure

Where figures drawn on two or more sheets are intended to form one whole figure, the figures on the several sheets shall be so arranged that the whole figure can be assembled without concealing any part of the partial figures.

Partial figures drawn on separate sheets must always be capable of being linked edge to edge, that is to say no figure may contain parts of another.

The case may arise where the parts of a whole figure are drawn on a single sheet following a layout different from that of the whole figure,

e.g. a very long figure divided into several parts placed one above the other and not next to one another on a sheet. This practice is permitted. However, the relationship between the different figures must be clear and unambiguous. It is therefore recommended that a scaled-down figure be included showing the whole formed by the partial figures and indicating the positions of the sections shown.

6. Prohibited matter The provisions as to the omission of prohibited matter within the meaning of Rule 48(1)(a) (see A-III, 8.1, and F-II, 7.2) also apply to drawings.

Statements or other matter of the type referred to under Rule 48(1)(c) (see F-II, 7.4) which are likely to appear in drawings are in particular various kinds of advertising, e.g. where the applicant includes in the drawing obvious business or departmental markings or a reference to an industrial design or model, whether registered or not. By doing so, matter would be introduced which is clearly irrelevant or unnecessary, which is expressly prohibited by Rule 48.

7. Executing of drawings

7.1 Drawings of lines and strokes

Rule 46(2)(a) sets certain standards for lines and strokes in the drawing, to permit satisfactory reproduction by the various means described in Rule 49(2).

The drawings must be executed in black. In all cases the thickness of the lines and strokes must take into account the scale, nature, execution and perfect legibility of the drawing and of the reproductions.

All lines must be drawn with the aid of drafting instruments save those for which no instrument exists, e.g. irregular diagrams and structures.

7.2 Shading

The use of shading in figures is allowed provided this assists in their understanding and is not so extensive as to impede legibility.

7.3 Cross-sections
7.3.1 Sectional diagrams

Where the figure is a cross-section on another figure, the latter should indicate the position and may indicate the viewing direction.

Each sectional figure should be capable of being quickly identified, especially where several cross-sections are made on the same figure,

e.g. by inscribing the words "Section on AB", or to avoid the use of lettering, by marking each end of the cross-section line on the diagram with a single Roman numeral. This number will be the same as the (Arabic) numeral identifying the figure where the section is illustrated. For example: "Figure 22 illustrates a section taken along the line XXII-XXII of Figure 21".

7.3.2 Hatching

A cross-section must be set out and drawn in the same manner as a normal view whose parts in cross-section are hatched with regularly spaced strokes, the space between strokes being chosen on the basis of the total area to be hatched.

Hatching should not impede the clear reading of the reference signs and leading lines. Consequently, if it is not possible to place references outside the hatched area, the hatching may be broken off wherever references are inserted. Certain types of hatching may be given a specific meaning.

7.4 Scale of drawings

If the scale of the figure is such that all the essential details would not be clearly distinguished if the figure is reproduced, electronically or photographically, with a linear reduction in size to two-thirds, then the figure must be redrawn to a larger scale, and if necessary the figure should be split up into partial figures so that a linear reduction in size to two-thirds is still intelligible.

The graphic representation of the scale of drawings in cases where its inclusion is considered useful must be such that it is still usable when the drawing is reproduced in reduced format. This excludes indications of size such as "actual size" or "scale ½", both on the drawings and in the description, in favour of graphic representations of the scale.

7.5 Numbers, letters and reference signs

Numbers, letters and reference signs and any other data given on the sheets of drawings, such as the numbering of figures, pages of the drawing, acceptable text matter, graduations on scales, etc., must be simple and clear, and not used in association with any brackets, inverted commas, circles or outlines whatsoever. Signs such as 6' and 35" are not regarded as including inverted commas and are therefore permitted.

Numbers, letters and reference signs should preferably all be laid out the same way up as the diagram so as to avoid having to rotate the page.

7.5.1 Leading lines

Leading lines are lines between reference signs and the details referred to. Such lines may be straight or curved and should be as short as possible. They must originate in the immediate proximity of the reference sign and extend at least as far as the features indicated.

Leading lines must be executed in the same way as lines in the drawing, viz. in accordance with Rule 46(2)(a).

7.5.2 Arrows

Arrows may be used at the end of the leading lines provided that their meaning is clear. They may indicate a number of points:

(i) a freestanding arrow indicates the entire section towards which it points; (ii) an arrow touching a line indicates the surface shown by the line looking along the direction of the arrow.

7.5.3 Height of the numbers and letters in the drawings

Under Rule 46(2)(g), a minimum size of 0.32 cm is required for all numbers and letters used on the drawings so that their reduction in size to two-thirds remains easily legible.

The Latin alphabet should normally be used for letters. The Greek alphabet is to be accepted however where it is customarily used, e.g. to indicate angles, wavelengths, etc.

7.5.4 Consistent use of reference signs as between description, claims and drawings

Reference signs not mentioned in the description and claims may not appear in the drawing, and vice versa.

Reference signs appearing in the drawing must be given in the description and the claims taken as a whole. As regards use of these signs in the claims, reference should be made to F-IV, 4.19.

Features of a drawing should not be designated by a reference in cases where the feature itself has not been described. This situation may arise as a result of amendments to the description involving the deletion of pages or whole paragraphs. One solution would be to strike out on the drawing reference signs which have been deleted in the description. Such corrections would have to be made in accordance with Rule 49(12).

Where for any reason a figure is deleted then of course the applicant or proprietor ought to delete all reference signs relating solely to that figure appearing in the description and claims.

In the case of applications dealing with complex subjects and incorporating a large number of drawings, a reference key may be attached to the end of the description. This key may take whatever form is appropriate and contain all the reference signs together with the designation of the features which they indicate. This method could have the advantage of standardising the terminology used in the description.

7.5.5 Consistent use of reference signs as between drawings The same features, when denoted by reference signs, must, throughout the application, be denoted by the same signs.

There would be considerable confusion if a single feature were allocated different reference signs in the various drawings. However, where several variants of an invention are described, each with reference to a particular figure, and where each variant contains features whose function is the same or basically the same, the features may, if this is indicated in the description, be identified by reference numbers made up of the number of the figure to which it relates followed by the number of the feature, which is the same for all variants, so that a single number is formed, e.g. the common feature "15" would be indicated by "115" in Fig. 1 while the corresponding feature would be indicated by "215" in Fig. 2.This system has the advantage that an individual feature and the figure on which it is to be considered can be indicated at the same time. It can also make complex cases involving many pages of drawings easier to read. Instead of the common reference sign being prefixed by the number of a figure, it may, when the individual variants are described with reference to particular groups of figures, be prefixed by the number of the particular variant to which it relates; this should be explained in the description.

7.6 Variations in proportions

Elements of the same figure must be in proportion to each other, unless a difference in proportion is indispensable for the clarity of the figure.

As a preferred alternative to a difference in proportion within one figure for the purpose of achieving the necessary clarity, a supplementary figure may be added giving a larger-scale illustration of the element of the initial figure. In such cases it is recommended that the enlarged element shown in the second figure be surrounded by a finely drawn or "dot-dash" circle in the first figure pinpointing its location without obscuring the figure.

8. Text matter on drawings It should first be noted that Rule 46(2)(d) and (g) also applies to text matter on the drawings.

For indications of the type "section on AB", see A-IX, 7.3.1.

The drawings must not contain text matter, except, when absolutely indispensable, a single word or a few words.

Where text matter is deemed indispensable for understanding the drawing, a minimum of words should be used, and a space free of all lines of drawings should be left around them for the translation.

As regards the justification for text matter on drawings, see F-II, 5.1.

9. Conventional symbols Known devices may be illustrated by symbols which have a universally recognised conventional meaning, provided no further detail is essential for understanding the subject-matter of the invention. Other signs and symbols may be used on condition that they are not likely to be confused with existing conventional symbols, that they are readily identifiable, i.e. simple, and providing that they are clearly explained in the text of the description.

Different types of hatching may also have different conventional meanings as regards the nature of a material seen in cross-section.

10. Amendments to drawings Amendments of the drawings are permitted, as well as of the other documents. These amendments may be made at the request of the party concerned or at the request of the EPO. The amendments may concern either clerical errors or more substantial changes. Amendments to drawings are, in general, subject to the same rules as apply in respect of amendments to other application documents and therefore do not require further analysis here. Reference may be made to A-III, 16; A-V, 2; B-XI, 8; C-III, 2; C-IV, 5; Part H, in particular H-II, 2 and H-III, 2.

The general rule governing the admissibility of amendments, which the examiner must always bear in mind, is that they must not extend the content of the application as filed, i.e. they must not have the effect of introducing new material.

If drawings which depart substantially from the physical requirements laid down in the Rules are filed in order to establish a particular date of filing or retain a priority date, the Receiving Section will permit such drawings to be amended or replaced so as to provide drawings complying with the Rules, provided that it is clear that no new material is thereby introduced into the application. In view of this proviso, applicants should take care that any "informal" drawings which they file clearly show all the features necessary to illustrate the invention.

11. Graphic forms of presentation not considered as drawings

11.1 Chemical and mathematical formulae

Chemical or mathematical formulae may be written by hand or drawn if necessary, but it is recommended that appropriate aids such as stencils or transfers be used. For practical reasons, formulae may be grouped together on one or more sheets annexed to the description and paginated with it. It is recommended in such cases that each formula be designated by a reference sign and the description should contain references to these formulae whenever necessary.

The chemical or mathematical formulae must employ symbols in general use and must be drawn in such a way that they are completely unambiguous. Figures, letters and signs which are not typed must be legible and identical in form in the various formulae, irrespective of the document in which they appear.

Chemical or mathematical formulae appearing in the text of the application or patent must have symbols, the capital letters of which are at least 0.21 cm high. Where they appear on sheets of drawings, these symbols must be at least 0.32 cm high.

All mathematical symbols used in a formula which appears in a description, in an annex or on sheets of drawings must be explained in the description, unless their significance is clear from the context. In any case, the mathematical symbols used may be collated in a list.
