Different methods to make Patent Drawings

A patent is an exclusionary grant of intellectual property rights, awarded by the government through a patent office for a limited period of time. The right is given by the government for an individual invention, which is not done by the other person before. It is the monopoly of an individual which is used by him in any way. The time limit for the use of patent is 20 years starting from the date on which the application for the patent was filed, after which it is used or sell by anybody. It is safest property of an individual. Everyone who invents a new process, machine part, chemical formula, new research in biology etc. should get the patent of his invention so that it is not stolen by other person.
People who file their application for patent should be careful that the invention is not already done.  The invention should be done for the first time. If the invention has already been done then your application will be rejected.  Three things are required by the person while submitting application that are: it must be a novel, relevant Patent Drawings and the subject matter must be in detail. If any document is missing, then you will not be able to get a patent. Drawings are of different types like: Mechanical drawings, drawings of medical devices, drawings used in biotechnological field etc. You can make these drawings own your own through various methods like: drawings from scanned images, by making flow charts, complex graphs, line drawings, by sketching, by taking photographs etc. Line drawings are those which consist of straight and curved lines placed against a background, to represent two dimensional or three dimensional images. It is the most fundamental art of drawing. In making the line drawings you can use lines colors, shading and textures. Dots can also be used in addition to lines. These drawings should be made with a pencil and should be made on the white paper. It is easier to erase the drawings with a pencil rather than a pen.
You make these drawings own your own if and only if you are good in making drawings. Some people thought of saving money by making drawings themselves. This can be both beneficial as well as can act as throne in getting a patent of your application if your drawings are not proper or insufficient drawings. So one should hire a technical expert who can make your drawings efficiently, as Patent illustration is equally important as other documents.

Does investing in professional patent drawing services make sense?

Patent Illustrations are wonderful for a patent application, but they don’t always do the invention justice if you are trying to capture the attention of a prospective licensee, or if you are trying to convince a buyer to place orders or sell the invention in their store.
Patent Illustrations and other types of invention drawings, such as 3D renderings and photo realistic virtual prototypes serve different purposes.  These drawings are done by using different techniques like by using Auto CAD software, by taking photographs, solidwork files and drawings from rough sketches.
CAD (computer-aided drafting or design) is a software used by inventors, architects, and other design professionals to visualize inventions, products, tools, machinery, and other devices. CAD programs provide a way of modeling these products in 2D or 3D perspectives. Modern CAD software is easy to use. It produces accurate drawings. A CAD program will enable us to construct an accurate, three dimensional (3D) representation model of the presentation model within the computer. A 3D model is typically built by using and modifying basic geometric building blocks, such as boxes, cylinders, planes, and custom-defined shapes.
Photographs or photomicrographs are acceptable as formal drawings in utility applications if they are used to show fine and irregular or natural structures that are not capable of being illustrated with black line Patent Drawings - for example, electrophoresis gels, blots, autoradiographs, cell cultures, histological tissue cross sections, animals, plants, in vivo imaging, thin layer chromatography plates, metallurgical microstructures, textiles, and crystalline structures. Photography cannot be used for illustrating non tangible inventions and graphical representations, such as schematic diagrams, charts, etc. In design applications, acceptable photographs include those that show subtle ornamental effects. We use a digital camera and 35 mm film camera. A photograph can be converted into a line drawing by putting a piece of paper of it and tracing it with pencil or, by scanning it into a computer and tracing it with a CAD program. 
The quick pen or pencil sketches allow the designer to try out several ideas and zero in on the most likely layouts before beginning a project. We make rough sketches of the images and show it to the customer. Please click HERE to Order your Patent Drawings & Illustrations.
