You can put anything you want in a provisional application. Photos (even color photos) are frequently filed in regular utility applications too, but they don't reproduce well, so examiners will often require you to submit line drawings. (Still, a fair number of patents issue with crappy, hard-to-see photos, so it's not a guarantee that you'll have to do ...

For 2d drawings- Draftsight. For 3d drawings- google sketchup. These two software are available for free to use. You may refer to this link to understand the importance of patent drawings in a patent specification:http://www.invntree.com/blogs/patent-drawings-and-their-importance-in-a-patent-specification

I agree Eric Shain. In fact, this kind of diagrams are quite popular en communication protocol related patents, where interactions between sender and receiver have a sequential order. For example, figures 3, 4 & 5 in Amazon patent US6675196; figure 2 in ATEN patent US7716404B2; or figure 2 in patent application US2004/0100945 A1. Sometimes, you can even ...

The MPEP says reference characters are preferably numerical. Patent applications do not usually have "chapters" and there is no need to invent a convention like that. As mentioned, even numbers let you add a number later without worrying about re-numbering but renumbering would not be needed anyway. That is not true of drawings - they need to be in order. ...

Yes you can use MS Paint, but it isn't a good choice. Paint is a painting program which means it edits pixels. Thus its output when printed tends to look blocky and low quality. Much better is a vector drawing application. These print out at high resolution and allow scaling without degradation. If you have access to Microsoft Office, then you will find ...

Can I use Microsoft Paint for drawings? Yes. There is no legal restriction on what software you use to produce the drawings initially. As long as the final product complies with the requirements of 37 CFR 1.84 (which basically requires clear line drawings), you should be fine. Moreover, there is no requirement for vector drawings. While these are ...

In the U.S. drawings must be black and white only (no grayscale). For utility patent applications, any type of shading is typically fine (stipple or linear). However, the shading rules for design patent applications are often more strict, or at least they are enforced more strictly.

This is the type of question that's probably best answered in consultation with a lawyer. It's hard for me to give you a helpful response that isn't specific legal advice. The risks of infringing (or even possibly infringing) a patent include a lawsuit in which you have to defend yourself against the accusations. If you're challenged with a lawsuit (i.e.,...

Disclaimer: the following is just personal opinion. Always talk to your attorney for professional legal advices. You should read through all the claims and check if the specification & diagram substantiate the claims. If the specification and the claims only describe the preferred implementation but does not describe alternative approaches that are ...

For a European application, the answer is also yes, but only if the drawing (alone) contains enough detail to provide some technical teaching to the skilled person. The decision you identified, T204/83, was one of the earliest EPO Board of Appeal decisions on this point, and effectively established the rules about drawings as prior art. The important ...

For reasons no one can explain, Google provides two different sites for viewing patents www.google.com/patents and patents.google.com. Only patents.google.com reliably shows patent figures. I would suggest, however, that you seriously consider using The Lens for patent searching. Here is US9476133 on The Lens. You'll find the entire PDF with figures. The ...

The purpose of drawings is to help explain the invention, including ensuring it is enabled. Consequently, you should include any drawings that would be useful for the reader to this end. If no drawings would be useful, then there is no obligation to include any. If the invention subsists in how the known elements are connected together, then this could well ...

An excellent free 3-D drawing tool is OnShape. It is free and runs within the browser so it works on any computer. Surprisingly capable. You can also generate 2D drawings. Much better than SketchUp for precision drawing. The website provides plenty of tutorials also. Unfortunately, OnShape changed their policies and now the free license doesn't provide for ...

Diagrams, illustrations, photos and graphs are all allowed in a patent application. They are referred to as drawings under 35 U.S.C 113: The applicant shall furnish a drawing where necessary for the understanding of the subject matter sought to be patented. Note from the U.S.C clause above that the purpose of any drawing is only to facilitate the ...

The more complicated we make to understand drawings then there are high chances that even the examiner will get confused and issue an office action on it. The basic necessity of patent application is it should enable a person skilled in the art to understand. Using numbers than characters are preferable.

I would expect that a drawing that conforms to USPTO drawing requirements (black and white comes to mind, exceptions for color is accepted only under documented conditions). A search of patents.google.com would produce the examples provided by user=David. If you suspect that something is prohibited, searching the relevant USPTO requirements (in this case ...

By law, patent applications need to include at least one patent drawing if the object or process is capable of being rendered in an illustration. However, it’s always worthwhile to try and include a patent drawing if at all possible, even if for a particular patent application it’s not strictly required. For example, if you’re claiming a method or process a ...

I used MS Paint for my first provisional patent application. One hint is to also get Paint.Net. MS Paint can add a 'fog' of pixels around parts every time you make a change or copy. Running the drawing through Noise reduction a few times in Paint.Net will get rid of this. Paint.Net will also resize images much better. For my second PPA I used SketchUp, ...

There is no one way to do this. As long as your drawings, when viewed in light of the description, are clear, there should be no problem. Thus using a dashed line to artificially divide the piece into the two constituent portions is an entirely reasonable approach. It would also be reasonable to use an exploded view, showing the separate parts, or use cross-...

If you are submitting a patent application to the U.S. Patent Office, then according to the Manual of Patent Examining Procedure 608(p): (1) Reference characters (numerals are preferred), sheet numbers, and view numbers must be plain and legible, and must not be used in association with brackets or inverted commas, or enclosed within outlines, e.g., ...

I'm assuming you're drawing it digitally and not by hand, personally if by hand I would use small down arrows to say it's a lower level X. Digitally, maybe something along the lines of X_, X-, or X~?

"Changes to Implement Eighteen-Month Publication of Patent Applications" (which introduced the current publication regime) gives some explanation of the meaning of "material mistake": The phrase "material mistake" means a mistake that affects the public's ability to appreciate the technical disclosure of the patent application publication or determine the ...

SolidWorks, Alibre and Sketchup etc can be used. Please visit this site for a similar discussion.

A drawing can certainly act a prior art on its own. The MPEP section on Drawings as Prior Art states (citations omitted): Drawings and pictures can anticipate claims if they clearly show the structure which is claimed. However, the picture must show all the claimed structural features and how they are put together. The origin of the drawing is immaterial. ...

Big difference in electronics. An electrical diagram show the sections of a circuit in a flowchart style without regard to physical space or connection of individual components. A schematic shows (from left to right)the signal path and every individual component in it's relationship to the other components, including it's type, rating, polarity, etc. One ...

No, those terms really do not have special distinct meanings in patent law (cf. comprising or consisting of). Generally however, the term "diagrammatic drawing" might be used for a simplified drawing which somewhat resembles the object, whereas the term "schematic drawing" might indicate something more abstract, having simply boxes or abstract symbols for ...

Go to "http://worldwide.espacenet.com/" and find the application, and find the drawings under "Mosaics"(there are two pages of drawings). I am not sure is it acceptable to provide a direct link in Ask patents, otherwise I could provide the direct link. :-)

SketchUp Make is the free version and works great. I filed my second provisional patent application using drawings created with SketchUp. You can download thousands of models and take parts or shapes from them, ready made. At the time I started on my first provisional, all I had was MicroSoft Paint. SketchUp makes it tremendously simpler and easier. Change ...
