Fact pattern scenario(1)

The claimant

•

KatzBrew is a leading craft beer manufacturer with 
nationwide reputation for its conventional beer offering

•

Launches new Pineapple beer, sold in 440ml cans and 4x4 can 
cardboard packaging – first foray into fruit-flavoured beer 
market

•

Deliberate departure from previous packaging strategy 

•

Multi-million £ advertising push 

•

Proves to be a hit in the marketplace, sells over £20 million 
over a 2 year period, 99% through retail outlets, ca. 50% 
supermarkets

4

Fact pattern scenario (2)

Registration strategy

•

Registered figurative trade mark consisting of a ‘flattened’ 2D 
representation of the Pineapple beer packaging

•

Filed in

Class 32 (beer; fruit-flavoured beer; craft beer) 

Class 30 (fruit beverages; flavourings; syrups)

Class 33 (alcoholic beverages other than beer, incl. cider, 
spirits, cocktails)

Class 35 (retail services; online marketplace services)

Class 43 (bar and hospitality services)

•

Specifications drafted broadly, capturing products/ services 
not in current pipeline

•

Email from Head of Legal to Brand Team: “

We should assume 

fast follower activity in this space – recommend filing as widely as 
possible to create a barrier to entry

.”

•

Internal commercial email: “

We’ll never go into (e.g.) spirits or 

mixers, but a wide spec puts us in a stronger position if other 
retail brands go down the pineapple route

.”

•

Strategy note (Board pack extract): “

Objective is to ‘ringfence’ the 

pineapple concept in alcohol and adjacent categories to block 
others from moving in

.”

Fact pattern scenario (3)

The defendant

Discount supermarket Crumps has a well-known strategy of 
producing ‘dupes’ just far enough away to avoid infringement

Spots success of KatzBrew product and instructs marketing team 
to launch a ‘dupe’ pineapple beer

Mimics “descriptive” indicators on the packaging (including 
pineapple imagery) but with different distribution, switches order 
of words and uses inherently distinctive CRUMPS name in 
expectation this will avoid infringement

KatzBrew alleges trade mark infringement based on confusion 
and reputation/ unfair advantage, Crumps fights back with a 
counter-challenge that Katz’ broad trade mark registrations are 
invalid due to lack of intention to use across their scope

Case law (1)

Thatchers v Aldi (CoA decision Jan 2025)

- High Court – no infringement; Aldi’s lemon cider may have 

been inspired by Thatchers and created a mental association, 
but it was not similar enough, misleading enough, or 
exploitative enough to amount to trade mark infringement or 
passing off – reflecting historic approach of English Courts

- Court of Appeal – overturned and found infringement based 

on taking unfair advantage of reputation:

-

Similarity understated by original judge

-

“Link” not accidental – central to Aldi strategy

-

Aldi made zero investment in marketing yet sold large 
quantities = objective evidence of unfair advantage

-

Intent of limited relevance

Case law (2)

Skykick (SC decision Nov 2024)

Sky commenced trade mark infringement and passing off 
proceedings against SkyKick in 2016

In defence, SkyKick argued that the huge breadth of 
goods/services covered by Sky’s registrations indicated they had 
been filed without a genuine intention to use the marks for all 
the goods/services covered, rendering them invalid on the 
grounds of bad faith

UK Supreme Court agreed – it held no intention to use a trade 
mark for some or all goods/ services applied for may result in the 
(**

partial

**) cancellation of a registration on the grounds it was 

filed in bad faith

Fact Pattern (Canada)

11

Your client, PharmaCo, has applied in Canada to register 
REDI-TREAT for prescription pharmaceutical preparations. 

The application has been opposed by a competitor, 
MediCo, based on its prior rights in the trademark READY 
CURE, also used in association with prescription 
pharmaceutical preparations.

PharmaCo seeks advice on whether it should decline to file the evidence, and then seek to file it as fresh 
evidence on an appeal to the Federal Court (if the Board’s decision is unfavourable).

PharmaCo intends to rely on a survey of 
dispensing pharmacists to demonstrate that there 
is no likelihood of confusion between the parties’ 
trademarks among this group.

The survey will likely not be completed before 
PharmaCo’s evidence deadline and may not be 
available until several months later. 

12

Issue 1: Opposition Appeal Procedure

Bottom line: it may be possible to file evidence on appeal, but for
the most part it is more prudent to seek case management and
attempt to set deadlines through that process—even where the
other side does not consent.

A party is no longer entitled to file fresh evidence on appeal as of right.

Opposition Board now has the authority to designate proceedings as case-managed.

Leave to file new evidence is not always granted:

• Leave granted: 

Products Unlimited, Inc v Five Seasons Comfort Limited

, 2026 FC 

48 (transitional period, no prejudice)

• Leave refused: 

Enteractive Media Inc. v. Gamechanger Media, Inc

., 2026 FC 843 

(lack of credibility, inadequate explanation of delay)

Issue 2: Admissibility of Survey Evidence

Canadian Courts and the Opposition Board are skeptical of expert evidence which 
is directed towards likelihood of confusion. 

Expert evidence relating to surveys has been characterized as an exception to this, 
but is still approached with “caution”: 

Masterpiece Inc. v Alavida Lifestyles Inc

, 2011 

SCC 27

Online Surveys: 

Promotion in Motion, Inc v Hershey Chocolate & Confectionery LLC

, 

2026 FCA 40 

Bottom Line: Survey evidence can be admissible subject
to strict requirements relating to reliability and validity.
There is always a risk that they could be excluded.
However, online surveys are still possible.

14

Issue 2: Admissibility of Survey Evidence

Explanation

Issue

Validity Issues

Priming bias

“The right questions” were not put to the 
survey participants

No “person in the loop”

The questions were not put to the participants 
“in the right way”

Availability of a “back button”

The questions were not put “in the right 
circumstances” to participants

Reliability Issues

Unclear if in-person survey would produce 
same results

Replicability

“[A]ctual Canadian Swiss-chocolate consuming 
population.”

Relevant population

“Fundamental Issue”

The inability of the experts to “ensure that the 
identity of study participants was 
unquestioned” or to “control the survey 
environment and testing parameters”

Design insufficient to address hearsay problem

Issue 3: Relevant Populations for Pharmaceuticals

Confusion test is hypothetical: it doesn’t matter if patients may 
not actually see the trademarks at issue.

Even where a patient’s choice as a consumer is relatively small, 
that choice is still relevant.

Relevant population for prescription pharmaceuticals includes physicians, 
pharmacists, AND patients: 

Samsung Bioepis Co, Ltd. v. Novartis AG

, 2025 

FCA 212 

Bottom line: even if the survey is admissible, its focus on
dispensing pharmacists means that it likely won’t be
determinative, and may not be afforded much weight.
