As feared my drawings were not accepted, too much grey, which isn't surprising as they were actually modified sketches.. I can't possibly go back to the drawing board, meaning starting from scratch. What's the most efficient and cost effective way to recover the main lines of my drawings and leave out all the grey areas? I was thinking about transparent paper in order to follow the main lines and leave out the rest, but any idea appreciated. Thanks

Can you provide more context?

Did you file a utility/non-provisional application? Did you get a communication from the PTO immediately after filing? If so, what was the paper called, and what exactly did it say?

Can you provide more context?

I applied for a UK patent, don't have the letter with me at present but it roughly said, as clearly written in the Application Guide to be fair, that shades should not be used, nor grey, only well-defined black lines. As I reported in a previous post, here are their DOs and DONTs as far as drawings are concerned:

DOs

-Do use black, well-defined lines on one side only of a white
A4 size page (21 x 29.7cm), with margins of at least 2.0cm
on the left-hand side, 2.0cm on the top, 1.5cm on the right
and 1.0cm on the bottom, so we can make good-quality
copies.

-Do number your drawing pages in order, at the top of each
page (but below the margin) in the middle. For instance, if
you have two drawing pages, they should be numbered 1
of 2 and 2 of 2 (ie 1/2 and 2/2).

-Do use reference numbers or letters, which must be at
least 0.3cm high, to relate parts of your drawings to parts
of your written description.

-Do join any reference numbers or letters to the
corresponding feature using a clear, continuous line.

-Do produce extra drawings to show other versions of your
invention.

DON’Ts

-Don’t use a coloured or lined sheet.

-Don’t use coloured ink, pencil or greyscale.

-Don’t draw a frame to show the margins.

-Don’t put anything in the margins or use borders
or frames.

-Don’t write descriptive text on the drawings.

-Don’t use too much shading.

-Don’t fold your drawings.

-Don’t create ‘engineering-type’ drawings showing

construction lines, materials or dimensions.

While my drawings might admittedly have been grey and shady, here's an example: http://i240.photobucket.com/albums/ff29/crowning73/fingerdrawing.jpg

I'll try later today the transparent paper method but if anyone in the meantime can share some tips & tricks don't hesitate.. Ta

Alistair:  There is a thread in "filing and prosecution" started by TataBox way back on 23 Oct 09.  There were some good tips/suggestions in that thread (good enough that I printed it out for use in this situation) that may be helpful to you.
