BAYKO Registered Designs

Until I visited the Liverpool Maritime Museum recently, I'd no idea that the “Registered Design” process even existed. As far as I understand it, without going into the same sort of detail and level of innovation that is required to justify a patent, you can register a design, focusing on the shape and appearance of the item, as an aid to prevent competitors copying your product…
…it's effectively a form of copyright.
Detailed below is a batch of BAYKO design registrations, all dated May 5th, 1949, which were granted to Plimpton to protect parts [not previously featured in either of the patents' documentation] from being copied.
The date is a little strange, as some of the parts concerned were actually launched onto the market some 11 years earlier, non-the-less, Plimpton clearly took the question of 'copy cat' products seriously at this time.
The images below, shown against a pale yellow background, show photographs of the “Registered Designs”, complete with their seals, held in the Liverpool Maritime Museum.
The museum also has other documents which refer to a further 3 registered designs for which they hold no documentation…
…the 3 images shown against a pale green background are all shown courtesy of the Public Records Office, Kew and are the 3 documents referred to above.
The document shown against a pale blue background [courtesy of the Public Records Office] was processed as a “Registered Design” at the same time as the other 9 items, but for some reason the Balustrade didn't even rate a mention in the correspondence held by the Liverpool Maritime Museum.
 
The individual documents below need no further introduction, so will get none…

“Registered Design” #858,341 - PINNACLE ROOF
Registered Design #858341 - PINNACLE ROOF
Perhaps surprisingly, there is no mutual cross reference to #858,352, the Pinnacle Platform.

“Registered Design” #858,344 - SPAN
Registered Design #858344 - SPAN

“Registered Design” #858,345 - DOME
Registered Design #858345 - DOME

“Registered Design” #858,347 - TURRET [Long]
Registered Design #858347 - TURRET [Long]
Presumably Plimpton received advice that there was no need to register the other three Turret shapes - this would suffice.

“Registered Design” #858,348 - WALL BRICK
Copy of the Registered Design document - Wall Brick
This is the first of 4 pages, more accurately 2 pairs of pages, which have 'mutual disclaimers' printed on their reverse sides : -
“The registration of this design shall not interfere with the use by any person of the design No. 858351
when copyright in that design has ceased.”
…#858,351 is the Balustrade.

“Registered Design” #858,350 - BAY WINDOW COVER
Registered Design #858350 - BAY WINDOW COVER
This is the second of 4 pages, more accurately 2 pairs of pages, which have 'mutual disclaimers' printed on their reverse sides : -
“The registration of this design shall not interfere with the use by any person of the design No. 858352
when copyright in that design has ceased.”
…#858,352 is the Pinnacle Platform.

“Registered Design” #858,351- BALUSTRADE
Copy of the Registered Design document - Balustrade
This is the third of 4 pages, more accurately 2 pairs of pages, which have 'mutual disclaimers' printed on their reverse sides : -
“The registration of this design shall not interfere with the use by any person of the design No. 858348
when copyright in that design has ceased.”
…#858,348 is the Wall Brick.
I'm struggling to get to grips with the failure to register either the Gate, or its Matching Balustrade - were Plimpton advised that this was enough?
I don't know why, but this is the one which was not mentioned in the documentation in the Liverpool Maritime Museum - probably a cock-up!

“Registered Design” #858,352 - PINNACLE PLATFORM
Copy of the Registered Design document - Pinnacle Platform
This is the last of 4 pages, more accurately 2 pairs of pages, which have 'mutual disclaimers' printed on their reverse sides : -
“The registration of this design shall not interfere with the use by any person of the design No. 858350
when copyright in that design has ceased.”
…#858,350 is the Bay Window Cover.
More surprisingly perhaps, there is no mutual cross reference to #858,341, the Pinnacle Roof.

“Registered Design” #858,353 - CRAZY PAVING
Registered Design #858353 - CRAZY PAVING
I wonder where the mid 1950s change to the double nipple version sits in this respect?

“Registered Design” #858,354 - END BRICK
Copy of the Registered Design document - End Brick

The list of potentially innovative parts not included in these registrations is quite lengthy. The lack of any basic Roofing components may be related to the BAYKO Patents, but not so the others : -
Canopies. [either style]
Corner Bricks and Full Corner Bricks.
Curved Bricks and Curved Windows.
Garage Doors. [A.K.A. Opening Doors]
Opening Windows.
Pillars. [1-Brick, 2-Brick or 3-Brick]
Side Bricks and Side Windows.
Steps, Side Steps and Platforms.
Finally in this train of thought, Mr. MECCANO apparently showed no interest in this area, unless you know better…
The Design Registration renewal prompt letter
One last piece of information on BAYKO's Registered Designs…
The Registered Design refusal letter
…they each had to be renewed annually to maintain the protection…
…for the princely sum of £10 each.
On March 3rd, 1959, A. J. Davies of Liverpool, the patent agents that Plimpton used, wrote to remind them of the need to renew this protection [left].
The hand written note in the lower left corner makes clear Plimpton Director, R. J. Cowell's instructions not to renew…
…the resultant letter [right] shows the intended rejection of the renewal and the necessary instructions to A. J. Davies.
Given the date this correspondence took place, and of course the decision itself, it all adds to the evidence of a climate of decline and retrenchment within Plimpton Engineering leading up to the MECCANO takeover.
