"Even if (as the (appellant) contended) the word 'Kettle'
and the symbol of a cauldron, although each was marked 'TM'
for trade mark, did not in themselves exclusively identify
the (respondent's) goods for 'a significant number of
consumers in the relevant market' (Johnson and Johnson
Australia Pty Ltd v Sterling Pharma-ceuticals Pty Ltd (1991)
[1991] FCA 310; 30 FCR 326 at 336, per Lockhart J), there can be no
doubt on the evidence that its packet, including that word
and symbol together with all the other features I have
mentioned, did identify its potato chips for a great many
people. It had sold millions of packets so marked. The
(appellant's) choice of a packet design so closely
resembling the (respondent's) is eloquent and expert
testimony to the attractive power of its combination of
features. Once the (appellant) made that choice, even if it
acted honestly in doing so (and in all the circumstances I
do not think it did), it came under an obligation to take
particular care to ensure that its product was adequately
distinguished from that of the (respondent). Lord Oliver of
Aylmerton put the matter strongly, with reference to a not
dissimilar context, in Reckitt and Colman Products Ltd v
Borden Inc. (1991) 1 W.L.R. 419 at 507-508; (1990) 1 All
ER 873 at 887 (a passage cited by Davies J in R. and C.
Products Pty Ltd v S.C. Johnson and Sons Pty Ltd (1993) 42
FCR 188 at 194):
'In the end the question comes down not to whether the
respondents are entitled to a monopoly in the sale of
lemon juice in natural size lemon-shaped containers
but whether the appellants, in deliberately adopting,
out of all the many possible shapes of container, a
container having the most immediately striking feature
of the respondent's get-up, have taken sufficient
steps to distinguish their product from that of the
respondents. As Roma LJ observed in Payton and Co.
Ltd v Snelling, Lampard and Co. Ltd (1900) 17 RPC 48
at 56:
"when one person has used certain leading
features, though common to the trade, if another
person is going to put goods on the market,
having the same leading features, he should take
extra care by the distinguishing features he is
going to put on his goods, to see that the goods
can be really distinguished . . .."
I stress the words "to see the goods can be really
distinguished" . . .'
I have reached the clear conclusion that the (appellant) was
guilty of passing-off, as well as contravention of s. 52 of
the Trade Practices Act."
