Color Drawing Petitions, Part II

My last post (When are color drawings acceptable? ) discussed a few Decisions on Color Drawing Petitions. Today I'll discuss a few more.

13/143,209 - Color Drawings Petition DENIED: In Jul. 2011, the Applicant filed a Petition for Color Drawings in 13/143, 209 ("Electromagnetic Radiation Mapping System"). The Petition stated:
Applicant asserts that the color found in the attached Figures is significant to the understanding of the invention. The necessity for the Color Drawings is to clearly show the maps and graphs of the figures.
In Mar. 2012, before an Art Unit was assigned, the Petition was Decided by a Petitions Examiner in the Office of Petitions. The Petition was denied, and the decision summarily stated that "the Office has determined that color drawings and photographs are not necessary for an understanding of the invention."

13/031,293 - Color Drawings Petition DENIED: In Feb. 2011, the Applicant for 13/031,293 ("Method and System for Detecting Light") filed the application and a Color Drawings Petition.The petition included the following explanation:
Applicant asserts that the color found in the attached Figures is significant to the understanding of the invention. The necessity for the Color Drawings is to distinguish the different lines.

In Mar. 2012, after being assigned to an Art Unit (1735) but before being docketed to an Examiner, a Petitions Attorney in the Office of Petitions denied the petition. The Decision explained as follows:
The Office has determined that color drawings or photographs are not the only practical medium by which to disclose in a printed utility patent the subject matter to be patented. As such, color drawings or photographs are not necessary for an understanding of the invention sought to be patented.
13/200,784 - Color Drawings Petition GRANTED: In Aug. 2007, the Applicant filed application 13/200,784 ("Method And System For Dynamic, Three-dimensional Geological Interpretation And Modeling"). The specification described one of the drawings, FIG. 16, as "exhibit[ing] integrating stratigraphic erosional rules into the present geological interpretation system."

The Applicant filed a Petition for Color Drawings two years later, though before the application was docketed to an Examiner. The Petition stated:
Applicant believes the detail contained within the drawings cannot be fully captured using black and white drawings ... The present disclosure allows the analyzing and interpreting of geological information associated with a geologic region [and] creation of three-dimensional graphic displays [of the information]. Accordingly, the color figures support properly conveying the form of the graphical displays.
At Notice of Allowance, the Petition was undecided. After the issue fee was paid, the Petition was granted by a Quality Control Specialist in the Publications Branch. The Decision indicated that "the petition was accompanied by all of the required fees and drawings" and "the specification contains the appropriate language."

13/200,784 - Color Drawings Petition GRANTED: The Applicant for 13/200,784 ("Interferometric Modulation Devices Having Triangular Subpixels") filed the application and a Color Drawings Petition in Sep. 2011. The petition included the following explanation:
The color drawings are believed to be the most practical method (and may be the only practical method) of accurately illustrating the different subpixel colors, groupings of subpixel colors, etc. Some of these drawings (Figs. 11A through 11C) not only depict different subpixel colors and groupings of subpixel layers, but also depict different groupings of subpixel colors underneath an "M1" layer.
In Feb. 2012, after being assigned to an Art Unit (2873) but before being docketed to an Examiner, a Senior Petitions Attorney in the Office of Petitions granted the petition. The Decision did not comment on the Applicant's explanation, but noted that the petition was accompanied "by all of the required fees and drawings" and that the specification included "the appropriate language."

My two cents: I'm not surprised to see Applicants filing Color Petitions for graphs and charts. The use of color can certainly make complicated graphs and charts easier to understand. However, color isn't the only way to convey that information. For example, I've seen black and white charts that use different types of dashed lines for different data series, or Xs and Os for the data points, etc.

Maybe this was the reason why the Petition in the first and second xamples above were denied. Hard to say, as no explanation was given.

The third example would be a little harder to do in black and white, but you could still use different types of fill instead of color. I think the last example comes closest to "only practical medium" standard set out in the CFR. Yes, you could distinguish the subpixels with different type of fill. But this particular drawing has a lot of different regions close together, so that would probably be a mess. So, color makes sense.

However, as I read the Petition Decision on this subpixels application, the Petition wasn't really granted on the merits. That is, the Petition doesn't say "the Office has determined that color is necessary." It just says the Applicant checked all the right boxes.

These eight Color Drawing Petition Decisions (this post and the last) are such a tiny sample size that it's hard to draw any real conclusions about what it takes to get Color Drawings accepted. That said, I wonder if one factor is the branch of the PTO that looks at the Petition. A Petitions Examiner looked at 3 of these 8 Petitions, and 2 of those 3 were denied. And the single one granted by a Petitions Examiner was the drawing with the most persuasive reason for color. In contrast, all 5 of the Petitions processed by something other than the Petitions Office were granted with virtually no explanation.

When are color drawings acceptable? A review of some Petition Decisions

The patent rules in 37 CFR §1.84 provide for color drawings "on rare occasions" when "necessary as the only practical medium by which to disclose the subject matter sought to be patented." I've always wondered how the PTO interprets this requirement. The answer isn't readily available, since color drawings require a petition, and there is no database of petition decisions equivalent to the database of Board of Appeals decisions. But I do run across Color Drawing Petitions from time to time, so in today's post I'll discuss an admittedly very small and random subset of decisions on Color Drawings Petitions. Later I'll follow up with another post discussing a few more of these decisions. 

 11/925,065 - Color Drawings Petition GRANTED Jun. 2010: The Applicant for 11/925,065 filed an application with a petition to accept 3 of the 6 drawings in color. The application was titled "Transmitting Information Effectively in Server/Client Network". The black & white version of one of the color drawings, from from the patent publication, is shown below:

As an explanation for why color was necessary, the Applicant stated:
...the use of color drawings is necessary to differentiate the information and the direction of travel of the information in the server/client network. The use of color drawings for these features of the present invention is considered essential.
After being assigned to an Art Unit, but before examination began, a Quality Assurance Specialist in T.C. 2400 granted the petition. The Decision did not comment on the sufficiency of the Applicant's explanation,  noting only that conditions (i), (ii), and (iii) of §1.84(a)(2) were met.

12/288,158 - Color Drawings Petition GRANTED Aug. 2010: The Applicant for 12/288,158 filed an application ("NLP-Based Entity Recognition and Disambiguation") with a petition to accept several user interface screen shots as color drawings. The black & white version of one of these drawings, from the patent publication, is shown below:
The petition did not include any explanation for why color was necessary. A few months after the Petition was filed, a Quality Assurance Specialist in TC 2100 denied the petition for this reason. The Applicant filed another Petition, and this time explained that "the color drawings are necessary to particularly point out and support Applicants' claimed invention." The same Q.A. Specialist granted the second petition, noting only the petition did contain the explanation required by §1.84.

11/495,229 - Color Drawings Petition Granted Jun. 2007: The Applicant for 11/495,229 filed an application ("Interactive Computer Simulation Enhanced Exercise Machine") with a petition to accept color photographs. The black & white version of one of these photographs, from the patent publication, is shown below:
As an explanation for why color was necessary, the Petition stated:
Color drawings are the only practical medium by which to disclose the simulated environment developed and generated by the disclosed subject matter of to the patent... Such details and contrast between the environment objects are only provided in color and would be lacking in a black & white photograph.
Six months after filing, the Petition was granted by a Supervisory Patent Examiner in T.C. 3700. The SPE treated the Petition as one to accept Color Photographs, since it referred to both §1.84(a) and §1.84(b) and included copies of the photographs in both black & white and color. The Decision did not comment on the sufficient of the Applicant's reason for color. Instead, the SPE simply noted that the Applicant had complied with the color photograph requirements of §1.84(b) by submitting the appropriate fee, a statement in the spec referring to color drawings, three sets of color drawings, and "a black and white photocopy accurately depicting, to the extent  possible, the subject matter shown in the color drawing."

13/033,384 - Color Drawings Petition GRANTED Mar. 2011: The Applicant for 13/033,384 filed an application ("Method for Embedding Secret Message into PNG Image") with a petition to accept several drawings in color. The specification described two of the color drawings as showing "an image before a secret message is embedded" and "the same image ... after the secret message is embedded." The black & white version of these drawings, from the patent publication, is shown below:
The Petition explained that "color drawings are believed to be the only practical medium by which to disclose the subject matter sought to be patented." Only a month after the Petition was filed, a Quality Assurance Specialist in T.C. 2400 granted the Petition. The Decision did not comment on the sufficiency of the Applicant's explanation,  noting only that conditions (i), (ii), and (iii) of §1.84(a)(2) were met.

My two cents: Seriously? You really think you need color drawings for a block diagram, a run-of-the-mill user interface, and a screen shot of a exercise simulation? The only one of these four for which color seems necessary is the last one, the one illustrating embedding a secret message. Although I can't see any difference in the publication between before and after the embedding, I can imagine that such a difference could only be expressed in color.

But there's no way you need color for the block diagram of the computer network -- the drawing already
uses different dashed lines to distinguish the difference in direction! As for the second example, not only is color not strictly necessary for the user interface, I don't even think it adds anything useful over a line drawing. Finally, the screen shot of the exercise simulation looks terrible, and line drawings would have shown the features much better.

What's the thinking here? Do patent practitioners submit color drawings simply because the drawings provided by the client are in color? Or is the rationale to save money? Note that the petition fee is only $130, and it wouldn't surprise me that a complicated user interface or screen shot would cost more than $130 to prepare as a line drawing. 

I think the PTO should provide some guidance on what is an acceptable reason for color drawings. Is the bar for the "necessary as the only practical medium" requirement of §1.84 really this low?
