<\/span><\/h2>\n\n\n\na. Do Not Admit of Direct Reproduction<\/strong><\/p>\n\n\n\nIn case a patent application is rejected citing \u201cDo Not Admit of Direct Reproduction<\/strong>\u201d as the reason, it means the applicant filed rough sketches\/drawings directly to the concerned patent office. This, however, is an incorrect method of filing. Applicants must create and file proper black and white line drawings, which are preferred by most jurisdictions. Besides line drawings, applicants can also use colored or grayscale pictures for specific patents.<\/p>\n\n\n\nb. Contain Unnecessary Textual Matter<\/strong><\/p>\n\n\n\nWhen a patent drawing is rejected due to unnecessary textual matter, it means that the submitted drawing included frivolous text. In order to avoid such errors, applicants must not include any unnecessary text or number in the patent drawing.<\/p>\n\n\n\n
c. Not Executed in Durable Black Color; Lines are not Uniformly Thick and Well-Defined<\/strong><\/p>\n\n\n\nThis error is one of the major reasons for most patent rejections and OAs. One way to avoid such errors is to create drawings wherein the lines have durable black color, are uniformly thick, and can withstand the pressure of handling several copies of patent drawings.<\/p>\n\n\n\n
d. Contain Cross-Sections not Properly Hatched<\/strong><\/p>\n\n\n\nIn order to understand this error, we need to first visualize the invention\/product. When we section a part of the product, we divide it into several subparts, each with its own sectioned surfaces. These surfaces need to be shown with a hatch filing where different hatch patterns can be used to indicate different surfaces. It is thus essential to understand hatch patterns and how they can be used to differentiate among the surfaces and material of different parts in the drawings.<\/p>\n\n\n\n
e. Would Not be Properly Distinguishable in Reduced Reproduction<\/strong><\/p>\n\n\n\nThis is a common point of objection in patent drawings and is often mentioned in OAs, especially in patent drawings that have complex and minute details. In order to avoid this error, while filing a patent, the drawings should be reduced in size to two-thirds during reproduction. Further, indications such as actual size or scale \u00bd are not allowed in patent drawings as they lose their meaning when reproduced in a distinct format.<\/p>\n\n\n\n
f. Contain Numbers and Letters of Height Less Than 0.32 cm<\/strong><\/p>\n\n\n\nApplicants must use the appropriate text size in patent drawings to avoid rejections. As per the PCT guidelines, the size of the text should not be less than 0.32 cm.<\/p>\n\n\n\n
g. Contain Figures on Two or More Sheets which Form a Single Complete Figure But which are Not Able to be Assembled without Concealing Parts Thereof<\/strong><\/p>\n\n\n\nSometimes, it is difficult to fit a figure in a single sheet. This usually happens in flow diagrams, piping and instrumentation diagrams (P&IDs), electrical circuits, etc. In order to make such figures ready for filing, applicants must split the figures into different sheets by drawing connections among the parts so that they can be seen as a single figure.<\/p>\n\n\n\n
h. Contain Figures which are not Properly Arranged and Clearly Separated<\/strong><\/p>\n\n\n\nWhen an applicant tries to include multiple figures in one sheet, the drawings appear messy. This makes it difficult for the patent examiner to recognize the actual claimed or essential details and leads to objection to the formal drawings. Thus, it is important to properly arrange the views to ensure that the patent drawings are error-free.<\/p>\n\n\n\n
i. Contain Different Figures Not Numbered in Consecutive Arabic Numerals<\/strong><\/p>\n\n\n\nAfter placing all patent drawings in the correct order, the different figures should be numbered in Arabic numerals in continuation. For instance, the first drawing should be denoted as FIG. 1, the second one as FIG. 2, and so on. It is crucial to number all figures in sequence to avoid any objection.<\/p>\n\n\n\n
j. Drawings are not Arranged in an Upright Position, Clearly Separated from One Another<\/strong><\/p>\n\n\n\nWhether the figures in a patent drawing are in portrait or landscape view, it is important to keep all the figures in an upright position to avoid patent rejection. This position ensures hassle-free readability of the patent drawing.<\/p>\n\n\n\n
