Technically registration is still a legal requirement, even though
a copyright notice is not.
However, the main practical effect of registration is that it allows you
to collect actual damages for infringement. Without registration, you
can only collect statutory damages, though they can be fairly substantial.

Just for reference, here is a list of when copyrights run
out in various situations. Corrections/comments welcome.
**************************************************
DATE OF WORK: Published before 1923
PROTECTED FROM: In public domain
TERM: None
**************************************************
DATE OF WORK: Published from 1923 - 63
PROTECTED FROM: When published with notice [3]
TERM: 28 years + could be renewed for 47 years,
now extended by 20 years for a total renewal
of 67 years. If not so renewed, now in
public domain
**************************************************
DATE OF WORK: Published from 1964 - 77

for first term;

second term
**************************************************
DATE OF WORK: Created before 1-1-78 but not published

Notes:
[1] Term of joint works is measured by life of the
longest-lived author.
[2] Works for hire, anonymous and pseudonymous
works also have this term. 17 U.S.C. § 302(c).
[3] Under the 1909 Act, works published without
notice went into the public domain upon
publication. Works published without notice
between 1-1-78 and 3-1-89, effective date of
the Berne Convention Implementation Act, retained
copyright only if, e.g., registration was made
within five years. 17 U.S.C. § 405.

This seems to have emerged from another newsgroup so the context of the

perform reverse engineering of anything (and I have done more than my fair
share of it - by neccessity) should be on clear ground as far as IP issues
are concerned.
My own reverse engineering work was always for a client who owned the
equipment and IP rights but had lost the documentation for systems that
needed to be modified. If you are doing it for reasons other than that then
the wicket is getting very sticky.

The Semiconductor Chip Protection Act is not relevant; the masks[/quote]
could be covered as works of art.
As far as age goes, you are correct - if an item is old enough, then
notice would be needed.
Without registration, collection of statutory damages would be rather
difficult as one would have to prove ownership and priority.
Registration is equivalent to "overkill" proof. |

A loud noise might scare them a few times but pretty soon they will
get used to it and keep coming. Squirrels do quite well in urban
settings with lots of scary stuff going on around them.
Since this is an electrical group, something electrical involving a high
voltage
source, with one pole being the bird perch, and the other pole being the
support pole for the feeder comes to mind. Do follow local electrical
codes though.

Along the lines of your original idea, go to Google or eBay and type
in "Personal Siren". You should find an amazing number of personal
protector alarms with 115 dB electronic sirens for cheap prices.
Next you have to take this apart and run two small wires (like speaker
cable) from indoors to outdoors. I would put the siren part outdoors
and mount the battery and a pushbutton switch (you need a pushbutton
switch - like a doorbell button) indoors. The battery holder you can
get from Radio Shack. You might need to do a bit of soldering so
either learn it yourself or get a friend to help.
