<div dir="ltr"><div>I just got back a set of drawings from my draftsperson. I always have to explain the same stuff over and over again, so I am consolidating all my views of the right way to do drawings in a memo that I can include with the drawings the first time. Here is a first draft. <b>What are your hot buttons?</b> I'll add them (and then send the consolidated doc to folks that ask for it -- attachments won't circulate through the listserv) <br></div><div><br></div><div>

patent drawings.</p><div style="margin-left:40px">
</div><p class="MsoNormal" style="margin:12pt 0in 0.0001pt 40px;font-size:12pt;font-family:"Times New Roman""><b>BIG is better, white space is bad.</b><span>
</span>Always keep in mind that the goal is to show, to teach.<span> </span>In patent drawings, the drawings should almost
always be as big as they can be.<span> </span>White
space is bad.<span> </span>The required margins are:</p><div style="margin-left:40px">

</span></span></span>For A4, top 2.5cm, left 2.5cm, right 1.5cm,
bottom 1cm, leaving a site of 26.2cm×17cm.<span>
</span>Recommended maximum: top 4cm, left 4cm, right 3cm, bottom 3cm</p><div style="margin-left:40px">

<span style="font-size:12pt;font-family:"Times New Roman"">For 8 ½ ×11, same margins, leaving a sight of
17.6cm×24.4cm (6 15/16 × 9 5/8)</span>

<span style="font-size:12pt;font-family:"Times New Roman"">White space between the figures of a sheet
should be fairly small—not crowded, but as tight as reasonable.<span> </span>Every square centimeter of white space is a
wasted opportunity.</span>
</p><div style="margin-left:40px">
</div><p class="MsoNormal" style="margin:5pt 0in 0.0001pt 40px;font-size:12pt;font-family:"Times New Roman"">In almost all cases, the drawings should
come out to touch those margins at three of the four edges.</p><div style="margin-left:40px">
</div><p class="MsoNormal" style="margin:16pt 0in 0.0001pt 40px;font-size:12pt;font-family:"Times New Roman""><b>Placement of FIG legends</b>:</p><div style="margin-left:40px">

<span style="font-size:12pt;font-family:"Times New Roman"">If there’s a neutral white corner of the figure,
put the FIG legend there.<span> </span>Centering the
FIG legend as a matter of habit is wasted opportunity.<span> </span>If the size of the figure is reduced <b>at all</b> to accommodate the FIG legend,
then almost always something should move.<span>
</span>Sometimes it’s unavoidable, but rarely.</span>
</p><div style="margin-left:40px">
</div><p class="gmail-MsoListBullet2" style="margin:5pt 0in 0.0001pt 0.9134in;font-size:12pt;font-family:"Times New Roman""><span style="font-family:Symbol"><span>·<span style="font:7pt "Times New Roman""> </span></span></span>
<span style="font-size:12pt;font-family:"Times New Roman"">Avoid putting the FIG legend in the space
between two figures—that creates ambiguity.<span>
</span>Most of the time, the FIG legend should be somewhere away from the center
of the sheet, and <b>not</b> in the space
between figures, so that the designation of a figure is unambiguous.</span>

</div><p class="MsoNormal" style="margin:16pt 0in 0.0001pt 40px;font-size:12pt;font-family:"Times New Roman""><b>Layout of figures on sheets.</b><span>
</span>Pay attention to what the drawings are trying to show, and arrange the figures
on the sheets accordingly.<span> </span>Sometimes,
the goal is detail of one drawing.<span>
</span>Sometimes the goal is to show a storyboard, a time-sequence.<span> </span>For a detail, the individual drawing should
be big.<span> </span>For a storyboard, it’s OK to
make the drawings a little smaller so that they fit on a sheet to show the time
sequence—the time sequence is far more visible if the figures are on one sheet
than if they’re one-to-the-sheet</p><div style="margin-left:40px">
